I think we're just too paranoid here, do we really expect that the PS2 port without online could sold more(380,000 in NA alone) than this game? , thats BS. We all knew that Wii games relies on legs. And not most Wii owners dont own a PS3 and a 360 either, if they are then the sales was just only slight wider on the Wii but thats not the case here.
end of core gaming days prediction:
E3 2006-The beginning of the end. Wii introduced
E3 2008- Armageddon. Wii motion plus introduced. Wii Music. Reggie says Animal crossing was a core game. Massive disappointment. many Wii core gamers selling their Wii.
E3 2010- Tape runs out
