Other small studios such as Bohemia Interactive have already confirmed support for the rift. Big people in the industry such as John Carmack are behind this project, it cannot fail. :D
I would love to be able to use the rift in DCS, it would be my dream come true. Total immersion. It isn't complicated to integrate either, and performance loss would be low. The low latency head tracking built into the rift would also be great.
