Escalation is out and there are new maps to play in Call of Duty: Black Ops, but that doesn't matter to you. You don't play for the fun of exploring a new map and discovering new strategies -- you just want cold, hard progression points. If you can't level up from it, you're not interested.
Fortunately for you, Treyarch has your back; the company's kicked off a Double XP weekend, so everyone playing BlOps, in the new maps or elsewhere, picks up double the points the whole time. Whew! Close one there -- you almost had some fun in that new content completely outside of the standard XP grind.
