WiiMusic using WiiSpeak would make me even wanna pick it up. To be honest I'm not that interested in buying WiiMusic at the moment but if you added in WiiSpeak Audio into the mix we could get some killer jams out. Even though their is nothing really to it I would still pick the game up. But unfortunetly I don't think its compatable with WiiSpeak so I won't be picking it up.
So far this fall the only two Wii games I am buying are The Conduit and AnimalCrossing:CityFolk. Unless Pikmin3 makes a suprise appearance in the fall line-up. To be honest I'm more interested in HaloWars, Sonic Unleashed and stuff like Banjo hopefully its not complete crap!
