I don't see any reason that you couldn't have these titles on an Apple Console though. But it would probably depend on Apple making deals with the developers. I can see EA wanting their AAA titles to be listed on a special shelf away from all of the dross.
Apple would need to spend a fortune in hardware costs just to enable the current expectations of AAA titles, and even then they wouldn't be bringing anything to the table that Sony and MS aren't already.
Sony & MS will launch new consoles with some jaw dropping must have launch titles to push sales to "hardcore gamers". At the same time they wait to see which independent Apple/OUYA titles are becoming popular, approach the devs and get ports for their consoles.
As the price for the next gen Sony/MS consoles drop the reasons for buying the other consoles start to shrink because all of the best games are available on the PS4 anyway.
