The Vita has a promising project in development. Nicholas Marcelin announced recently that work on a project of his is in development and that he wants to release it on the PlayStation Vita.
Project Classic is a PlayStation Vita game for ps vita owners created by vita owners. Hence the codename, the game will be very reminiscent of classic 3D platforming games. The game has been in development for approximately one month now with hopes to be released around holiday season next year/ Early 2018.
We will likely hear more about this project as it continues development into 2017.
