I came back to MW3 this game is awesome
Aha! Don't worry guys, he's trolling.
They won't go back to COD4 since all these designers' prides are bigger than their brains. I'm not gonna be buying another Call of Duty unless they make some serious changes in the right direction. Probably will buy the next 3arc title but time will tell and I'll def wait to see reviews and lots of gameplay before making any decisions.
You're right though. Treyarch should go off to make non-COD games. I think it's apparent they're trying to stray away from it (probably bored) but when they try to be original when trapped inside the COD-box, it has some rough edges.
