err having "multi-platforming" online in which a ps3 player can vs. a pc player is such a stupid idea unless the ps3 player was using a usb keyboard and mouse. Having a player with a pc, using the keyboard and mouse verse a player with a controller is such a stupid idea as there would be no competition. Controllers have a complete disadvantage in terms of aiming/turning, jumping, crouching - more or less all movements compared to pc players. This would then lead to people using a keyboard and mouse for their ps3, if they were bothered, which is completely pointless as then there would be no need to buy it on ps3 as you'd basically be playing a pc version.
