Does it really matter? The fact that the PS Vita has sold that much is pretty bad. Not forgetting Vita has been on the market longer than the Wii U and even the Wii U sales have been closing up with the Vita. If Sony actually bothered to support the Vita, maybe sales would of been so much better, but they seem much more interested in the PS4. It's a shame because PS4 sales will continue to stay strong, but even then they still won't put the extra effort into the Vita.
