Nice spot. I hope they do bring Akimbo into Black Ops, it gives you a different style of play. But as in the picture, i reckon it will be just for pistols, the reason i think this is because i believe treyarch think having a primary and a shotgun or machine pistol as a secondary gives 'too much firepower'. So im guessing they are keeping the old Create-A-Class system (shotgun is primary etc).
This is just my guess, but i hope we do see a return of Akimbo.
