You will be missing alot if you dont get a ps3.
Dont listen to monatana he has a 360 only therefore he is somewhat of a fanboy(sorry its true)
Ratchet and clank is amazing you wont be able to play that
Haze as well
I would get the ps3. Why? Becuase I am the only one on the site that has all 3 and trust me get a ps3.
2008 end of year predictions:
PS3: 22M
360: 25M
wii: 40M
