Every major game studio is working with Occulus for future gaming programs. Go read a little bit Floob, better yet, watch Carmack's youtube video (you know, the guy who wrote Doom, all of the Quake titles, and made more $ in gaming before 1998 than most will in a lifetime) about the work he is doing with Rift. Regardless of what you think or feel, it's going to be the future of gaming, because the developers are making their long term future products require it. The cost will come down, remember that 300$ is for a developers kit, not a retail product.
I'll bet you that in 5 years or whatever your necro challenge is, that it'll be a retail product under 200$, and for at least 50% of the top 10 best selling games at the time, it'll be if not a requirement, something that is absolutely necessary to take full advantage of the games and be competitive with them.
Five years goes fast, I remember 2009, hell 1999 like it was yesterday on this bbs, but Rift's moving forward that fast IMO.
Over at Star Citizen they have an entire division in Canada working JUST on implementing Rift with their full release of Star Citizen and Squadron 42, once Rift is ready, they want to be ready. I read on their bbs that they purchased 50 developers kits just for the team from Star Citizen working on it. That says a lot IMO. FYI, the new version of Arena Commander for Star Citizen came out yesterday with TrackIR and 6dof working. It's amazing, I can literally point the gimbal turret on the top of my Hornet fighter out the right side window, and shoot enemy fighters as we're maneuvering and fighting. It's great, stick flies the fighter, head moves the view and guns, it's like the monocle on the AH64 apache for it's 30mm gun more or less. Can't wait for Occ Rift to be working.
