According to NeoGAF user ace3skoot, this is a brief information Leaked by Shacknews Pod Cast called Weekend Confirmed. Here are some details ace3skoot got from the podcast:
10 point allocation system replaces primary/secondary/grenades slot system
Guns, attachments, equipment, perks take up allocation points
for example you could have 2 primary weapons which would use most of your points and only have 1 perk.
Or No guns but lots of perks, so you could get a knife kill, steal a gun and make good on all the perks you choose.
New wager match variations.
Everyone starts with a machine pistol and 1 emp grenade, you have to disable and hack drones to get more kills, only way to get more emp grenades is to take them from another player.
I think this is a great addition to Black Ops, this will actually make classes unique and your own. Hopefully this will bring a new feel to the game and a new challenge.
All this info seems to have been under embargo and has been edited out the current podcast but to get the original head here.
