Forum:Call of Duty: Black Ops XP Bar?

Hi Everyone In Black Ops you must level up in order to unlock an then buy weapons, perks and killstreaks. But in the trailers and gameplay videos I have not a seen a XP bar that keeps track of your exprience. My question is: Will we have the possibility to see our XP bar ingame??like the ones in Cod 4, Waw, and Mw2? Thanks Everyone
