I don't feel like making a new thread every time something comes out so I will just make this.
There was a big expo tonight for this game..tons of new info released and gametrailers is uploading a lot of videos from it. They are cams but they are good enough:

3- UAV
4- Care package (ammo drop or a option for it to pick a random kill streak for you)
4- Counter UAV
5 - Predator missle (see some of the gametrailers videos for how this works)
5 - Sentry gun
6 - Precision air strike
7 - Helicopter
9 - Pave low (another type of helicopter)

Some other pics:

http://twitpic.com/hw7s7 Slight of hand is a perk 1 now
http://twitpic.com/hw7vd Shows some of the equipment you can use
http://twitpic.com/hw7zy Shotguns, handguns, machine pistols, and launchers for secondary weapons
http://twitpic.com/hw7zf Some sort of noob toob item for your secondary weapons
Many sources have confirmed suppressed snipers and shotguns

(you can see a suppressed shotgun if one of the gametrailers vids). Other attachments include red dot sight, heartbeat sensor, thermal scope, and more. You can also dual wield some weapons.
Some new perks include:
Bling (have 2 attachments)
Commando (greater range on knife attacks)
Scavenger (automatically take ammo and grenades from a dead enemy)
Marathon (infinite sprint)
Lightweight (move faster)
Cold blooded (no idea, possibly takes you off the heartbeat censor attachment)
Scrambler (no idea)
Hardline (kill streaks take 1 less kill)
A lot of old ones from cod4 like stopping power, juggernaut, slight of hand, steady aim, etc are still there.
There is also a death streak option...If you die 4 times in a row you can select "Copycat" Take the class of the person who just killed you so you might get some better weapons if your sucking. There is also a "painkiller" perk which gives you 3x health for the first 10 seconds of your spawn if you die 3 times in a row. I don't really like this one..
New level cap is 70, not 55 like cod4.
Game is released on November 10th, 2009
I will update this post as more info is released...
