"Why is it so impossible to believe that it's the Wii projects that are costing the 3rd parties... you know, like they are stating directly?"
They didn't say the Wii games were the reason they lost money, just that revenue was down from them.
Although some might have lost money, but those would have to have been pretty pricey games to lose money (Dead Space was a definite one), and those are not that common on the Wii (even though some think they are non-existent).
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
