Another historical trend to consider: components that don't come with the system itself rarely get much third-party support. The reason is simple: if the peripheral doesn't come with the system, then a great deal of the potential buyers will have to buy both the game AND the peripheral, which will drop the odds of the product selling well. Ergo developers will often shy away from non-pack-in peripherals. And even being a pack-in peripheral doesn't guarantee success of said peripheral: even the NES Zapper, which came with roughly 75% of the NES systems distributed in the US, had less than 20 games made which utilized it. There was nothing wrong with the Zapper; it worked exaclty the way it was supposed to and the games made for it were usually quite fun. Developers just didn't work with it, for whatever reason.
All that in mind, the PlayStation Eye (and 360 camera as well) is unlikely to get much support from third parties. Perhaps some token experimental games will be made for them, and casual use-it-if-you-have-it support for them, but I can't see them taking off at all. Potential though they have, they lack the appeal that the Wii Remote's IR camera has, in that they're not guaranteed peripherals and thus not guaranteed game sellers.
Sky Render - Sanity is for the weak.
