I spent a few hours with it today/tonight and I love it. The game is gorgeous, shooting mechanics are tight, co-op missions are a blast, customization is out of this world, and if you suck, the game doesn't hold your hand in competitive modes. Definitely going to be my go to shooter once it comes out. I can see myself wasting an absolute ton of time in the competitive modes. It feels more like Halo than Halo 4 did and I absolutely love it.

Sony is very wise getting into bed with Activision on this. Guaranteed huge seller.
