Most of the games are port and niche games that's a bad support,vita support was never good

And niche games are doing better on vita then 3ds

God Eater 2: Rage Burst, Digimon Cyber Sleuth, Sword Art Online: Lost Song, Minecraft and Super Robot Z3 released all in 2015 for PS Vita. Persona 4: Dancing All Night, SaGa 2015, KanColle Kai, Tokyo Xanadu... are all going to release in 2015. 
Bad support? PS Vita support is decent in Japan. 

No Metal gear solid,no Final fantasy,no kingdoms heart,no real monster hunter game vita need those games to boost it's sales so the install base increase and by that help niche games to sell better
