According to
Businessweek, Apple would be currently in talks with several game publishers, including Electronic Arts, to provide a set of popular games for the future iPhone. It would also prove that Apple could give third parties access to the iPhone, despite the "only from Apple" statement heard in January during the launch of the iPhone in January.
Games are already available from the iTunes Store for iPods, and nothing prevent Apple to offer similar titles for the iPhone in the future as everything is already on place. In addition, games for iPhone would of course be more realistic and graphically more stunning thanks to the iPhone hardware: the NVidia GPU is able to display 3D, in a much better way than the current iPods.
But beyond the iPhone, this rumor could also open up the game market for the Apple TV station. But one should also not get too much ecstatic, as the Apple TV hardware is far from being as game-oriented as the PS3, Wii or Xbox360.
