I've been looking forward to this launch imho, especially now with a Tesla Roadster is confirmed to be the payload.
Holding out hope Musk isn't evil or bad and that it is possible very very high up actors in SpaceX are the bad ones, some which could be very young and stupid to secretly give info away to clowns/NK.
It's a demo flight, first ever for the Falcon Heavy, so it could very well blow up. Because of this they don't want a real payload. Payload on the first Falcon 9 flight was a big wheel of cheese. Boils down because Musk wanted to send his car to space. If it survives the launch it will head towards Mars and inserted into a solar orbit.
