It's probably going to be a bit like the Wiimote. Fans will get excited about it but the real thing won't be able to do nearly as much as they imagined. At least not at first. But without bundling from launch it won't get the install base and thus won't get the third party support. I don't see this tech really working all that well for at least another five years anyway.
I found Malstrom's article on the subject to be quite interesting. The underperformance and such.
"Now, a fun game should always be easy to understand - you should be able to take one look at it and know what you have to do straight away. It should be so well constructed that you can tell at a glance what your goal is and, even if you don’t succeed, you’ll blame yourself rather than the game. Moreover, the people standing around watching the game have also got to be able to enjoy it." - Shiggy
