1) How often will you play? If you play a lot more, then Xbox 360 is probably your bet since the online gameplay is supposedly much better
2) What do your friends have? This is your main priority, of course you want to be able to play with your friends
3) Can you wait for the new map packs? If not, go with Xbox 360
4) IGNORING BLACK OPS, which console better suits your need? For example, do you need the Blu-Ray player on the PS3? Xbox 360 to ... stream some TV I guess?
Overall, I went with the PS3 but it's all up to you I guess
Just throwing this out there, seemingly a lot more girls have a ps3.
I prefer xbox 360, more games, blue ray is unnecessary, also the online is a lot better with xbox, and there's more players, which means games are more active.
Kinect is also, 1000x better than move.

If anyone is interested in playing some cod later tonight, gt is : Arcane Vespa.
I ended up getting a PS3 because that's what most of my friends had, and it's really fun playing with them. Also i had played PS3 a lot with my friends so i was used to the controller and stuff.
