Modern Warfare 2 Live Multiplayer Feed

Ooh there are lots of goodies in this trailer

For the guns, we got:
.44 Magnum
SCAR H
MP5K
AUG
AA-12
UMP 45 (EXTENDED MAG)
TAR 21 (FMJ)
I see an RPD on the ground over there...

New types of ammo (confirmed)
Supply drop and Predator Missle killstreaks
the killstreak icons are 3d and rotate
you can now throw knives at people
Multiple attachments on one gun (probably another perk)
host migration for the failyacht consoles
and that's all I could catch.

We'll undoubtedly hear more when ign or gametrailers comes out with an analysis
