I wouldn't go console specific. It's not like the games differ that greath. I would split it between Handhelds and Consoles though. Mainly becuase we don't need a bunch of whiny PS3 is better 360 is better brats. They can combine for discussion.
So bascially what I'm hearing his give the juggernauts their own forums, (Mario,COD,Halo,Pokemon etc,) leave general alone. Probably should, well yes give a 360 general forum and a ps3 general forum, which could used to host tournaments.
Then collagulate everything else?
