The "mysterious announcement" was just scheduling a press conference. It's scheduled for two hours from now; discussing before then is pretty pointless.
Falcon 9 First Stage recovery?
Every enigmatic thing Elon does or says is going to be excessively hyped at this point. I hope he doesn't blow the goodwill he has because of that...
First it was Bill Gates, then Steve Jobs, and now Elon Musk. Tech-world journalists need a protagonist.
Flagged, there's no substance at all to the article and any discussion at this point is just speculation and detracts from the value of this site.
Hyperloop ?
"Elon Musk will make an important SpaceX announcement today."
Looks like it's about SpaceX, probably another attempt?
He's going to use the Hyperloop to accelerate a spacecraft and use that inertia to shoot the rocket out of the atmosphere.
