I've heard lag isn't a problem, server crashes occurred on launch day but it's stabilized now. To compensate, the animations and effects are pretty simplistic and textures are low resolution. I can live with that, but knowing the average console gamer, I'm worried about the staying power of the game. There's a fair bit of Ramboism in the game currently, but I'm sure most of those people will start playing Battlefield: Bad Company 2 when it comes out.
Since picking up a PS3 last month, I've bought MW2, Uncharted 2, Borderlands and I'll be buying Demon's Souls today all as multiplayer games. I don't have time to play all those (most of the time I don't have time to play any) and I don't want to spend $60 on a game that I might not even start playing until the multiplayer community is already dead in the water.
