Do lots of people still play Battlefield Bad Company 2 on Xbox?

I was thinking about buying a used copy of BFBC 2 since I'm getting bored of Black Ops. Do lots of people still play online on xbox? How about on the Vietnam expansion pack?
Update: Let me clarify what I mean by "lots of people." All I want to know is if I'll be able to consistently get into games every time I search. That's it.
Update 2: And please, only answer if you've played recently and know what you're talking about.
