If you ask me, we're already getting a couple right within the launch window. That is if we're purely talking quality.
I think, personally, that NSMBU is "AAA", for sure. I also think that games like Rayman Legends and Lego City Undercover have "AAA" potential, as exclusives go. Then you've got games that have been CALLED "AAA" in the past, such as Batman, ACIII, ME3, Darksiders II and Black Ops 2. Then there's the upcoming Aliens: Colonial Marines, which will HOPEFULLY live up to the hype, as well as Pikmin 3, which I'd certainly hope is "AAA", like it's predecessors. And of course, depending on how you feel about it, Bayonetta 2.
So there's plenty of good candidates, I think.
