Virtua Fighter 5 unfortunately will not have online multiplayer on any system. They don't want to compromise perfection with the limits of internet latency. I heard that it will use the VF.Net service though--while it's not multiplayer, it tracks stats and replays and all this sort of stuff. I saw it in Japan, it's actually quite awesome if they're going to be bringing the whole VF.Net/VFTV to the consoles.
