So far my only complaints would be small map size and some doubts as to Killstreak balance. Other than that haven't had time to play enough to really state much else.
I'm guessing the small maps are to ensure you're always in the action but I think they've taken it too far. Not a deal-breaker but I don't like always feeling cramped - perhaps this is also a function of playing BF3 first recently then trying MW3, I'll wait a few days and see how I feel then.
Survival is great fun though and I do like the Spec Ops from the little I've played.
Try to be reasonable... its easier than you think...
