You all have pc,s so what you waiting for? there is a network called Kaillera for it online and mk1 arkade is available there stop waiting for ps3 release.And if its gonna get released on ps3, will be only latest final revision 5 since its best.
I play on kaillera a lot but its the lag and delay issues that get me. At least with the consoles the game will either run smooth or it will go slow (if it goes slow then i wont play lol)
