We've also learned, unfortunately, that this latest Call of Duty still won't support dedicated servers, instead relying on the hosted servers found in previous iterations of the game.

The biggest new addition to the game that we've heard of so far is the creation of Team Perks. These are perks that a team can work toward to earn. It is unclear whether this will be tied to clans or some other team system, but their inclusion could help push the game into a more team-driven title, something the premium Elite service is likely to tie into.

While we don't know the total number of team perks coming to Modern Warfare 3, we have been told four of them:

Stopping Power: Increased bullet damage.
Blast Shield: Unclear
Health Regen: Regenerate health over time.
Stun Protection: Prevent stunning from flash grenades.

New perks coming to Modern Warfare 3 include:

Blind Eye: This makes you immune to computer-controlled and player-controlled killstreaks. The pro version makes your launchers lock on faster and gives you extra bullet damage to vehicles.
Assassin: This makes you immune to UAV, thermal, and heartbeat sensors. The pro version also makes you immune to CUAV, EMP and no longer shows your name in red or the crosshair in red when you're targeted.
Point Guard: Every two assists count as a kill towards your killstreak.
Dead Silence: You make no noise.
Recon: Gives you a special kind of radar to spot enemies, most likely. We're not sure on this one.

We're not clear on how many or which previous perks will be coming to the game, but it sounds like the ones that do return will do some from Modern Warfare 2, not Black Ops.

There will also be a bevy of new killstreaks to play with in multiplayer. Here's the rundown on the latest thinking:

EMP Grenade: Temporarily takes out all area electronics.
Littlebird: A tiny remote-controlled helicopter.
Precision Airstrike: Calls in an airstrike on a targeted area.
Stealth bomber: Calls in a B2 Spirit to carpet bomb along a line designated by the player.
Remote Turret: A remote controlled turret.
Directional UAV: A UAV that can be directed into areas to scan for enemies.
Remote Mortar: Direct a mortar team using a zoomable camera view of the map to call in strikes.
Airdrop Trap: A booby-trapped airdrop.
Ammo Resupply: An ammo reloading airdrop.
Escort Airdrop: A protected airdrop.
Specialist Strike Package: This one remains a mystery to us.

While it's likely that some of the killstreaks will drop out or be added in, we've been told that the team has decided to remove the controversial Tactical Nuke killstreak from the game.

won't support dedicated servers

This could be for Xbox and PS3 players, as they really want dedicated servers. Maybe we will get them still.... can't say i am to bothered about the game though

402's been on twitter debunking some of this as untrue, mainly stopping power.
