2D Mario is in decline. Less than 42% sell-through for NSMB2

I highly doubt 2D Mario is in decline. Like everyone here already said, Nintendo games usually have amazing legs.(sexy)

But I wish they would try something different with their 2D Mario games. I didn't enjoy NSMB Wii and Super Mario 3D Land that much, it was kinda boring for my tastes.
