Apple recently unveiled a new Game Center web page detailing the features of the service and revealed that the 2nd Generation iPod touch will also be a Game Center-capable device. After delaying the Game Center release to iOS 4.1, Apple had previously announced that it would only be available on 3rd generation devices and newer. This latest development only leaves the first generation iPod touch and both the original iPhone and iPhone 3G out in the cold.
Game Center is launching soon with iOS 4.1 and already developers are committing to supporting it in their games. Forum member Project-79 has been maintaining a thread of assembled announcements and press releases from developers that will be supporting Game Center on (or soon after) launch. Notable titles include Flight Control [99¢], Angry Birds [99¢ / Free] and many others.
