Call of Duty 4 Map Pack

So, ive done some research on the CoD4 Map pack ( Creek, Broadcast, Chinatown and Killhouse) and cant work out if I should get it. Is it worth it for just 4 extra maps, when im getting CoD MW2 at chrstmas.

don't get it.. I have the map packs and they aren't that special. You get Killhouse in team tac, free for all, and cage match. So if you don't play those modes often you won't play killhouse.

If you were not getting MW2 I would say yes buy them. But once you get 2 you won't play 1 a lot anyway. Hell I traded mine in for 2
