Halo or MW3?

I kind of want both the Halo Anniversary Edition and Call of Duty: MW3. Although I really would rather get Battlefield 3 and Halo. I am just not so super excited about the CoD series these days. I need something like Battlefield, which requires much more teamwork and skill to play. So I think I will preorder Halo today through Amazon to get the $10 game credit they are offering. Which I will get it for free thanks to the $20 credit I got for buying Gears of War 3 and the $30 reward credit I have on my Amazon card. Then I can still get $20 off of Battlefield. Man I do love Amazon.
