First Multiplayer Trailer For Call Of Duty Black Ops 2

Huh. I'm more interested in what the perks are. Those usually make or break CoD for me (see, Ghost in Black Ops, Assassin in MW3, One Man Army in MW2).

Also, looks like the knife is a one hit kill again (which is very bad). But was it an equipment? I couldn't tell from the trailer.
