1. proprietary memory stick that let people avoid it and make the price more expensive
2.Most people who able to buy prefer Smartphone like iPhone (especially Japanese people who love iPhone so much)
3.Lack of Big triple A exclusive like Monster Hunter and Final Fantasy etc
4. Lack of support from SCEI (from exclusive game, and third party exclusive games ) due to the SONY limited on financial trouble.
5. Japan as the front market in gaming overall already decline.
6.Lack of support on the first year from Japanese developer
I would like PS Vita to survive, they have good third party title lately, but i depend on SONY, will they support it till the end or they just let it in on market as decent handled with a lot of third party support.
One way to make PS Vita survive in the west is to bring all the game form Japan to US or Europe.
