Do a search, you'll find plenty on the subject. Video games support higher than HD resolutions on PC's everyday. The Xbox is nothing more than a PC. We aren't talking about HD-DVD here, that's not how it works. The video chip scales the game to whatever screen resolutions that the video game and chip supports. In the Xbox world, the hardware supports 480i, 480p, 720p, and 1080i. So far, the software has supported 3/4 of those, with 1080i coming this month in Dragons Lair.
Anyway, lets keep this thread for 16:9 discussions and if we want to talk tech or anything OT, start a different thread. The original thread got kinda out of hand that way and many were hoping this would be a simple update thread when confirmed 16:9 titles were found.
