I stumbled across this recent (2month old) video, it gives a hint at what to expect in the consumer ready version of the Oculus Rift.

Put simply
-Reduced screen door effect (removing lines between rows/columns of pixels)
-Higher resolution (dual 1080p screens)
-Positional tracking (i.e. if you crouch, jump, or lie down, you can do the same in the virtual environment)

I'm soooo pumped/anxiously awaiting this device.
