It would be awesome, for sure. i feel like with the switch to next gen, us PS3 users have been a little neglected, or at least not had the same focus as the 360 users. still, I kinda like not having as many kids on PS3 online. seems like the PS3 crowd is a liiiitle bit more mature, even though we also have our glitchers and gimmicky schemes to deal with. just seems like the anecdotes we hear come mainly from the 360 camp...
but yeah, I'd love to play against a buddy who has a 360. not sure if Sony and MicroSoft will want that or not.. or if they've already exerted pressure on EA to not go down that path or not...
