The discussion over on the Myst and Obduction forums is about whether most of the people will need a new computer or not. The minimum hardware requirements are pretty high. See: Cyan Worlds’ Obduction July Release.
There is enough of a commotion about hardware the Cyan Worlds peeps have posted: Obduction VS. Hardware. Mike Dogherra explains his experience with the game. He doesn’t address the Oculus Rift aspect, which I think is why we see such high specs.
While I could be wrong, I think much of this is about Cyan covering their butts and controlling expectations. They do not want to get ripped on for giving people simulator sickness.
