All I can say is I hope they play it safe and just make a controller that is compatible with the Wii's slots, because I can't think of any other way this will work and still be fun. Since I lack a PS2 and thus haven't been able to pick up the previous games, I'll probably try and get this when it comes out, assuming they don't screw it up.

Oh, and they had better include Final Countdown by Europe.
