IMHO, the main difference would be in the "marketing points," in the sense that they'll attract different kind of people. While technically it's possible for castAR to do what Oculus does, Carmack and Elsworth names alone should show the type of early adopters for each products.
Without a doubt, castAR will close the kickstarter funding. So both of them are facing the chicken and egg problem, I believe castAR will have a huge problem here. To your "game changer" point, castAR is trying to reach a higher sky than Oculus.
I mean, I can see myself having a small space near my bed for Oculus and attaching it to the Steam Machine within a year or two. CastAR? Maybe 5 years ahead of its time? The current implementation of the magic wand worries me. From the video, the awkward looking Jenga-like game seems slow and not 1-to-1 interaction. Although it could be a "beta" thing, Oculus didn't have HD to begin with.
As gamer, I think HD Oculus would be a better purchase, and wait for castAR v2 or v3, I have serious doubt they'll reach mass market.
