Do these PS3 games still have active online communities?

I'm planning on re-buying a PS3 this holiday and I'd like to know if some old(ish) games I want still have enough people playing online. Would you be so kind as to help me?

How about:

- Resistance 1 & 2

- Battlefield: Bad Company 1 & 2

- Starhawk

- Warhawk

- Call of Duty 3, World at War, Modern Warfare 2 & 3

- Killzone 2 & 3

Thanks a bunch!

1) I think the servers for Resistance are now offline, not 100% sure on that though. Resistance 2 was dead when I played a year ago.

2) Not sure but BC2 is the best BF on PS3 so im sure its still popular.

3) Still a decent amount of people on.

4) Still a hardcore player base here

5) Call of Duty 3 will probably be a ghost town but the rest are probably still kicking.

6) Not sure, I imagine both are still playable though!
