Mario has always been a system seller, the's a difference between how the 2d and 3d games perform commercially, the 2d game sell over a long time they are the go to games during holidays and such hence why NSMBW was always in the charts every holiday since it's launch. In the long run the 2d games shift more systems but in the short term the 3d games move more units, people are harping on about needing support because they're looking at the short term, 3DW is a holiday release and will probably be the most sort out title through out December then about a month after that DK is released then soon after MK8 is released and so on.
That's 3DW's support, it'll sell well in the short term as wel as have legs to carry itself until the next first party title arrives.
