One word --
Mario.
Before SMG2 is just written off as a "level expansion pack" I would ask you to consider that EAD Tokyo will likely get another year to develop this at least with NSMB Wii probably selling for a long time to come.
So they have a loooooooooooooooot of time to polish the hell out of that and really make it a true sequel to Galaxy thanks to NSMB Wii. Just something to consider.
