The Unlosing Ranger
Mighty Strike-Out Slugger
I don't think that Sony will allow the Vita to really die. They have some thinking to do with regard to the proprietary game format and maybe even a bit of a price break, though it's really not overly priced. The issue I think is that people are tired of purchasing games over and over again for different systems. If they would create an app store (like apple) and allow people to purchase one and download to any sony device I think that they will bring interest back to the Vita and even the PS4...which I think is superior to the Xbox One, but will suffer in sales due to not having backwards compatibility and having to repurchase existing game libraries.
But they already do that, they have cross-buy. The thing is that it's up to the publisher to allow or disallow it, so not all games have that feature. But there's quite a bunch of games that when bought for PS3 give you the Vita version and vice-versa.
What they need to do is lower the price of their proprietary memory cards a lot further (that's THE thing people about the most) and bring the Vita TV over to the West eventually.
