Atleast core gamer is on a treat right now, but I doubt even core gamers wants to use the nunchuk wiimote combo, in just few hours of thinking and watching the experience videos I think the only wiimote control scheme was more fun like its more fun to play MKWii on a Wii wheel >.
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
