For our part, we're interested to see how a game that necessitates split-second timing will translate to the occasionally laggy world of online play. Sure, the "online mode" could just be you and a friend playing the same song and then comparing scores, but that hardly seems like fun. Another question: Won't our fingers cramp up entering our 12-note friend code on the Wii version? We kid, of course, we don't know that there will be specific GH friend codes. But we can dream.
