Cool maps, very detailed weapons and balanced.
Hacking will be hard, but on the long run will be achieved.
10 prestiges as always.
Hard but satisfying to do - Challenges.
70 levels
killstreaks - accumulative - the immortal ones: UAV, Counter UAV, predator drone, sentry gun, chopper, care package, emergency airdrop.
new ones, nuke will be changed or will stay but with more killstreak requirement. (25 was very easy to do imo), multi attack ? xD who knows? I just want them to surprise me

Perks...the same as always but no commando, I believe that they got the message - we (serious players) don't really like it. They might add a new one to replace it (I hope they don't fuk up the game with it.)
