You only need to do a little bit of research to realise that if the claims about frostbyte 2 are legit, and based on what I've seen I've no reason to think otherwise, hence, the technology alone is awesome, they finally got the small scale destruction going. Frostbyte 1 was in my opinion pony in its destruction.
I just don't see what MW3 is offering, its just more of the same, as it has been since MW. I can't believe how often thing caca gets lapped up by the general public, the changes are barely worth mentioning. Its a crap product, I played MW 1 + 2 and wasn't even amused, I actually found WaW to be more amusing, if only because it showed that the entire tech they're using is totally flawed.
Everything is hand scripted, the AI doesn't even exist really...
If you look at the multiplayer, on paper Battlefield has always been a more complex experience, so that's really the hurdle, making it an uncomplicated experience for the CoDtard's of the world.
