Battlefield 3? Modern warfare 3?

Sorry but DICE has much more experience than IW. Dice has been making games since 1992 and IW only started on 2002. I predict BF3 will get criticized positively more than MW3. MW3 will sell more due it's large fanbase. I will definitely buy BF3, as for MW3, i don't think an expansion pack is worth $60-$50.
