Not much new info, but some interesting quotes suggesting there's a lot more game support behind the scenes that has yet to be revealed:
On games: “Without getting into specific numbers, we are confident that a lot of games are going to support the Rift. Our developer kits are being shipped to basically every large developer in the world, and many of them are talking to us about the projects they want to integrate with our headset,” [Palmer] said.
“That said, we are leaving game announcements to developers. It’s really for them to announce, not us.”
UPDATE: Full interview now up.
