Could Nintendo do anything wrong with the 3DS that would allow the Vita to over take it in a few years?

Only way Vita will pass 3DS now tbh is if Nintendo stopped making and selling 3DS' and it's even questionable if Vita will then be able to sell as much as it let alone pass it as Vita is in a situation every handheld that took on the gameboy was in.
