Are people still playing Killzone 3 or Crysis 2 on psn?

I was going to pick one of these games up but I didn't know if anyone would still be on psn with all the new games that have came out. If there are not people playing on psn for Killzone 3 or Crysis 2 I was just going to pick up Modern Warfare 3.Are people still playing Killzone 3 or Crysis 2 on psn?
