SpaceX has been teasing on its website that "Something Big is Coming" on April 5, 2011. They also posted a teaser video...
It appears the announcement relates to their Falcon Heavy, which SpaceX describes as follows:
The Falcon Heavy will be SpaceX’s entry into the heavy lift launch vehicle category. Capable of lifting over 32,000 kg to Low Earth Orbit (LEO), and over 19,500 kg to Geostationary Transfer Orbit (GTO), the Falcon Heavy will compete with the largest commercial launchers now available. It consists of a standard Falcon 9 with two additional Falcon 9 first stages acting as liquid strap-on boosters. With the Falcon 9 first stage already designed to support the additional loads of this configuration and with common tanking and engines across both vehicles, development and operation of the Falcon Heavy will be highly cost-effective.
Length: 54.9 m (180 ft)
Width: 3.6 m (12 ft)
Mass: 885,000 kg (1,950 klb)
Thrust on liftoff: 15 MN (3,375 klbf)

Falcon Heavy will carry more payload to orbit or escape velocity than any vehicle in history, apart from the Saturn V moon rocket, which was decommissioned after the Apollo program.
In addition to the Saturn V, the Energia had a higher rated payload to orbit and lunar insertion...

To all Florida residents: Incoming Missiles!
More seriously, what happens if one goes off track and "lands" where it wasn't supposed to?

The same thing that happens if a rocket veers off course during launch, i.e. flight termination.
SpaceX's proposed landing site at the Cape is Complex 13, which is located away from populated areas. A recent environmental assessment noted:
Should there be a need to activate the FTS, it would occur over the open ocean and would result in a much smaller explosion and less debris.
...an anomaly on the landing pads such as an explosion could injure or kill wildlife found adjacent to the launch pad or within debris impact areas. However payloads would not be involved and the fuel load would be substantially less than a typical launch.
An improbable mishap from downrange would occur over the open ocean and would not likely jeopardize any wildlife, given the relatively low density of species within the surface waters of these open ocean areas. Debris from launch failures has a small potential to adversely affect managed fish species and their habitats in the vicinity of the project area.

From SpaceX:
When Falcon Heavy flies for the first time next year, it will be the most powerful operational rocket in the world by a factor of two. Here's an FH interstage being prepped at the rocket factory recently.

Has LZ-1 been upgraded to add additional booster landing pads and are there any aerial pics of the new configuration? (Google Maps still shows only the one pad.)
And when the Falcon Heavy boosters return to land at LZ-1 do they land at exactly the same time? (Based on this SpaceX video they will land simultaneously.)

The next two Falcon Heavy launches are slated for early 2019, carrying the Arabsat 6A communications satellite and U.S. Air Force's Space Test Program-2 (with The Planetary Society's LightSail 2).
The Swedish satellite company Ovzon and California-based ViaSat each have announced plans for Falcon Heavy launches between 2020 and 2022. And the Jet Propulsion Laboratory is considering the Falcon Heavy for the Europa Clipper.

You may be a better internet searcher than I am, but I couldn't see any of that on the SpaceX Falcon Heavy page.
I also seem to remember Elon Musk talking about a second launch between July - October, 2018. Why the delay? I realise there may have been technical issues arising from the first launch needing resolved; or perhaps some planned customer got cold feet. There are clearly many potential problems in developing a new rocket. I just like to keep track of how things are progressing, and SpaceX don't seem to be bending over backwards to do that.
It concerns me that if the second launch of a rocket which seemed to work perfectly has been delayed well beyond the original predictions, there must be grounds for significant scepticism about SpaceX predictions for the "BFR."

Another Falcon Heavy is also contracted to launch the Air Force's AFSPC-52 mission in late 2020.

SpaceX also stated prior to the launch of the Falcon Heavy that they had found the development of the vehicle to be more difficult than originally thought, and that the learning experience of Falcon Heavy led to their change of plans and the intention to focus on the BFR design.
The space industry also seems to have taken up cubesat technology that often piggyback other mission launch vehicles, meaning the Falcon Heavy, heavy lift performance, may be a somewhat niche ability that may not be required with any regularity.
Combine this with SpaceX prioritizing Crew Dragon preparation and BFR development could mean that SpaceX may be busy with other things.
Also, unlike NASA, SpaceX don't have any requirement to report plans and progress for activities, and national security and commercial in confidence requirements probably limit what they can say about future heavy lift missions.

Yes, but without predicted launch dates, those five entries look aspirational and need to be seen in the context of the original talk about a second launch in the second half of this year. However, I think you may have hit the nail on the head about SpaceX concentrating on Dragon and BFR — I hope I'm wrong to think of Falcon Heavy as a "Spruce Goose" and I will be delighted to see future FH launches.

Here are my photos from today's launch. I could not make it yesterday so a scrub was a blessing for me. Beautiful day and the sound from the Saturn V Center shook the stands way more than a shuttle launch from the same place. The landing was amazing and the sonic booms loud!

Though the core landed successfully, it was ultimately toppled by rough seas, SpaceX told The Verge.
Over the weekend, due to rough sea conditions, SpaceX's recovery team was unable to secure the center core booster for its return trip to Port Canaveral. As conditions worsened with eight to ten foot swells, the booster began to shift and ultimately was unable to remain upright. While we had hoped to bring the booster back intact, the safety of our team always takes precedence. We do not expect future missions to be impacted.

SpaceX is targeting today (Monday, June 24) for the next launch of its Falcon Heavy rocket from Complex 39A at NASA's Kennedy Space Center in Florida.
The primary launch window opens at 11:30 p.m. EDT, or 3:30 a.m. UTC on June 25, and closes at 3:30 a.m. EDT on June 25, or 7:30 a.m. UTC. A backup launch window opens on June 25 at 11:30 p.m. EDT, or 3:30 a.m. UTC on June 26, and closes at 3:30 a.m. EDT on June 26, or 7:30 a.m. UTC. Deployments will begin approximately 12 minutes after liftoff and end approximately 3 hours and 32 minutes after liftoff.
Falcon Heavy's side boosters for the STP-2 mission previously supported the Arabsat-6A mission in April 2019. Following booster separation, Falcon Heavy's two side boosters will attempt to land at SpaceX's Landing Zones 1 and 2 (LZ-1 and LZ-2) at Cape Canaveral Air Force Station in Florida. Falcon Heavy's center core will attempt to land on the "Of Course I Still Love You" droneship, which will be stationed in the Atlantic Ocean.

I set up for and was successful in capturing our view here at home (in Georgia) of the Falcon Heavy launch.
I had some low clouds roll in, so the early part of the flight was blocked, but it cleared the clouds just before side booster sep. The center core continued and you can see the boosters coming back.

During the SpaceX STP-2 webcast something peculiar looking was visible for fraction of a second at 1:37:23 on the right hand side of the screen.
Does anyone have an idea what that could be? I don't remember seeing something like that before. (Well, except in the Stargate movie.)

That is a view inside the second stage propellant tank, showing fuel slosh. SpaceX has shown it a few times on prior webcasts.

There are many YouTube videos of this for SpaceX rockets (as well as old Saturn 1 rockets). Fuel sloshing can cause serious problems. It actually doomed the second flight of the earlier Falcon 1 booster.

Had not seen this before.
From where is the illumination coming? Putting lights inside a propellant tank doesn't seem like a smart move to me.
