Is anyone really developing for the Rift outside of John Carmack? - Cool if so but I haven't really heard much of anything.
Not only TF2 as 005 said, but there are lots of indie games in development for it right now.
From the rumors I've heard, there could be some surprises at GDC next week. Oculus has been saying that they have some big-ish announcements.
