Why bringing this topic again? It doesnt matter what sells more at launch. The more important was the lifetime sell of each game. Wii fit in Japan sells 30,000-40,000 each week without changing its price since its launch in January(if thats the month). Thats show you something about Wii fit's sales...
And Ninendo already prove that their software sells with the likes of SSBB, Zelda, Mario Kart Wii and Metroid Prime 3 one game will never change that. It doesnt matter if GTA sells 20-30 million during this generation, it never changes the fact that there are more Wii games that have strong legs than HD console games.
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
