Because most Wii games are endloaded, and the ones that you mentioned are niche anyway. I mean why not compared it to Boom Blox or De Blob? I think those are the ones that have good examples than those...
P.S. Why you mentioned COD WAW? Its just only on its second week of sales yet.
edit: Boom Blox actually sell its only released this year while Protector of the Earth released over a year...
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
