Vita does not deserve this sales, but Sony does.
They made some bad decisions in developing process, like stupid memory card.
But this console has huge potential: front touch screen, rare touch pad, dual analogs. This console had everything what it takes to become great handheld, somehow it wasn't success.
In Japan probably because of Monster Hunter series moving to 3DS and lack of other handheld-like games.
In EU and US... I don't know, especially launch was good: Uncharted, Assassin's Creed, WipeOut, Need for Speed, Killzone....
Well... probably people prefer 3DS with much less power....
