It probably would have helped.
Although what I would have done is release SSBB and MkWii in different halves of the year but otherwise close to what you list...
Wii Fit early in the year was fine too...
I think the big issue was releasing Mk Wii and SSBB so close to each others and then releasing Wii Music and AC for the holydays.
a Wii Music/SSBB holydays with still AC/Mk Wii early in the year to boost hardware sales all year long would probably have done a lot better....
It seems to me the order the software was released was more a knee jerk reaction to try to eclipse GTA4 than a well thought out plan....( basically jeopardize the beginning of 2009 with weak 2008 holydays titles but steal GTA4 thunder).
PS3-Xbox360 gap : 1.5 millions and going up in PS3 favor !
PS3-Wii gap : 20 millions and going down !
