Move isn't really comparable to the PS Eye, neither technically nor in terms of software support. Right now, today, the Move controller already has enough games to make it worthwhile. Just based on what is out there now, today, I would heartily recommend getting it even if no other game were ever to be released for it.
Well... Sony's reasoning was the PSEye alone could not provide enough precision and versatility to do what the devs wanted. The additional Move controllers are supposed to complete the picture.
The amount of dev support and marketing dedicated to Move is certainly way over PSEye. But there's no guarantee that AntShaw will like any of them. ^_^
Other than the Move-enabled browser rumor, Sony has not talked much about Move non-games too. The entire effort is very focused on games now. Perhaps this is due to the management's decision to focus on gaming first. Or perhaps they are too busy with so many parallel projects (PSPx, Qriocity, 3D gaming and movies, etc.)
