They were letting people try them on at the Emerging Technologies booth at SIGGRAPH. You could get yourself one of the cheap passes and come down to Anaheim in a couple of weeks, I'm sure they'll have their latest revision.
I'm actually going to be in Anaheim the weekend of the 16th (Disneyland), but making it back down there a week later isn't going to work with my already planned vacation later. :/
If only I could find a way to convince my employer that this conference is related to the job at hand...
