References to gaming and a possible controller for the Apple TV have been discovered in the iOS 4.3 beta code, suggesting Apple may have learned a thing or two from Xbox Live and PSN, and is looking to take Game Center's offerings to the next level. The popularity of games on iOS has contributed to the huge success of the iPhone, iPad and iPod touch. Bringing games to the Apple TV could help create inroads for Apple into consumers' living rooms and mark a first step into competition with the likes of Microsoft, Sony and Nintendo -- even if it's a small one. Many expect the Apple TV to get apps like the other iOS devices, and putting some emphasis on games could be a good fit for the "hobby" set-top box.
