According to a TUAW report, there's a possibility that online gaming will be coming to the new Apple TV in iOS 4.3, and no, we're not talking about this Game Center, it may be something more interesting.
Some references were found in the latest iOS 4.3 beta which refer to “ATVThunder” and indicate online games and merchandising that will be soon be available on iTunes to your Apple TV 2G.
As TUAW notes, the new Apple TV is capable of running iOS games as it has the A4 CPU the same as iPad; which is a very capable gaming device. Anyway, the iOS 4.3 is about to go live for public, we'll have to wait to see. What do you think? Will you really play online games on Apple TV 2G? Let us know!
