Wow ur really stretching now, we don't even know how much 3DS sold in January, meaning that 39% figure is useless.

If we go with the 3DS VGChartz sales, Vita is definitely undertracked here! 

And if we go with hard numbers from VGChartz, and then percentages based on NPD, we'd be making a stupid argument.
