wow and here I was about to order the kit.. I imagine this is going to stump sales a lot, I mean if we have to run games at 60+ FPS to not feel drunk in game people are going to have to have super computers to really enjoy it...:S
I remember reading somewhere that Sony were saying (presumably in regards to Morpheus) that games developed for VR would have to lose some graphical whizz-bang but what you gain (VR) is worth the "loss".
You're right though, it is going to be the case for some time that getting the very best VR experience is going to require serious kit - those of us used to going into the graphics settings in games and automatically turning everything up to 11 will maybe have to compromise a bit more.
