The author of the OP apparently doesn't know anything about the big MP launches on the 360. Gear of War, Halo 3 and Gears of War 2 all has serious MP issues at launch that took weeks to iron out. Both Gears games are still a mess for competitive play, especially Gears 2 - Horde mode is pretty great, however.
I haven't had any issues playing Killzone 2 online yet, though at the same time, I don't doubt that others do. Finding a server that's not full has been my biggest issue.
