We'd been hearing rumours for a while, but this seems to be more and more legit. I do wish that @ned or someone official would release a press release explaining their position and what it means.
I hope that this is a good thing for everyone. Time will tell.
There'll be a live stream later tonight. None of this stuff will change overnight, the code-back-end stuff will (although depending on Tron's developer's prowess) take a long time.
