I have a feeling we're going to see many buggy launch games in any case...this system feels like it's in the same place as the DS...I don't think too many early DS games were buggy, but a lot of them were very simplistic and rushed. To pop out console games with super-ultra-HD-revolution-4eva graphics in such a short time span seems more likely to produce lots of bugs. Even in the case of Perfect Dark or Kameo, the games have been in development for a while, but actual Xbox 360 development probably didn't start until halfway through 2004 - definitely not for Kameo, since it was still slated for Xbox as of last E3.
Umm, that's way off-topic. I've always been interested in this series, but I'm a one-console person, and you have to own two just to play the two games in the series so far, so I'm definitely hoping Shenmue 3 comes to Revolution. I think it would be nice of Sega to release it on 360 for those who followed the series on the first Xbox, though.
