Well... But isn't the way that they solved the nausea problem that they managed to get very, very, very low latency between your head movements and those movements being translated to the image you see?
All the hardware improvements there presumably don't help if there isn't a different image to view when you move your head.
The reason Oculus took so long to announce a consumer version was largely tied to the fact they hadn't solved the nausea problem. Now they have.
