Since the Vita’s release, very few new games have been announced. However, one of the few games is the rather odd Dokuro. While very little is known, it is made by Gamearts who also made Ragnorok for the Vita, so it should be good. Despite this, the game is set for release on July 5th and will cost 2,400 yen ($30) for retail or 1,800 ($23) yen for digital.
Currently no word on a US release, but you can always import the Japanese version. If you happen to go this route, first run copies will come with a special cleaning cloth. However, no import site has it listed yet, so you might need to find another way to get it.
