Skyrim, then BF3, then MW3.
I played the hell out of Oblivion, so I'm most looking forward to Skyrim. I always liked Battlefield, ever since 1942 and still play BF2 and BFP4F - it just suits my style of play much better than COD, I like to snipe, and COD absolutely sucks for sniping.
I'll wait on one of my brothers buying MW3 then borrow it.
What about formats though?
I kinda side with the PS3 these days over the 360, and I'm not 100% sure that my PC would handle any of those games. Maybe should consider upgrading before that fateful date.
