The same. Vita's problem was a lack of direction and compelling titles. Vita went from:
For fans that like HD games -> PS360 gamers -> PS3 owners -> Weebs -> then finally a home for Indies. Sony never really knew what to with Vita. It's Software was composed of lesser versions of consoles games when it should have had its own original IP's.
Vita's death was a gross lack of direction. Most likely because SONY did not know why PSP was popular.
