I ordered this a couple days ago, but for the PC for $25 from Fry's.
I already have it for PS3, but for these kinds of games I prefer the MP on PC. Dedicated servers, more players, and I just have to use mouse and keyboard for online MP. And for this price, I couldn't say no. Thankfully I have a PC that can run it perfectly maxed out on DX10, and High with some things toned down on DX11.
This game will be glorious on PC, especially since I'm so sick of COD4, as I never bought MW2 on PC...and never will.
