Hard to say on an unreleased game, but generally speaking, the current MacBook Pros have very solid hardware and should be able to handle most modern games quite well.
But before you spend, I would question the wisdom of buying a Mac laptop (or any laptop for that matter) if one of the major uses for it will be gaming. For one thing, gaming on a laptop (just due to the form-factor) generally sucks and is not immersive. But beyond that, the machine you purchase from new is pretty much what you're stuck with. There is no way to upgrade the video card or CPU down the road.
For those reasons, I maintain a custom-built gaming PC strictly for playing games. My laptop is used for pretty much everything else. In this way, I find my laptops "age" more gracefully, and I don't regret having bought a particular model or not waiting for the next big thing.
Just something to think about, especially considering the cost differential between the low-end 15" model and the upper-end machines. For just a little more, you could have a pretty nice gaming rig, and a brand new MacBook Pro that is still quite capable.
