Warhawk Online Community

[JOKA_]

Hi

I'm trying to decide what games to get this holiday season and Warhawk is on my list.

Before buying I just wanted to know if any of you could tell me how large the online community is.  Since it online only i don't want to get screwed and have it turn out that there are only a few people on at a time.

 Also, do you think Call of Duty 4 is worth it if i'm planning to get Warhawk?  I only have so much time to play in a day.
