Well theres definately gonna be new Perks 
Probably will be partly set in Brazil.
Part will probably be set in a snowy environment.
Will have Navy Seals as playable.
Co-op campaign would be nice.
Some maps from CoD:MW would be cool, along with new maps obviously.
No Nub Tube until level 55 would be ace.
LOTS of new weapons and a custom camo option for your gun when 200 headshots are achieved.
More variety in air support.
