Trailer looks quite good - but then IW always made a good SP game. My only hope is that they sort out the MP side of things.
Will have to see how the multi-developer side of things goes - it could be a positive influence but then it could as easily have a negative effect on the game.
I will keep an eye on things but they are going to have to work hard to prove to me that they are worthy of my hard earned pennies - especially given that BF3 will be there clamouring for my attention...
The sooner you get behind, the longer you have to catch up.
