Kadokawa Games is developing Fate/stay night Realta Nua for PlayStation Vita, according to leaked reports from the latest issue of New Type. The game features animation from Ufotable and will be released on November 29, priced ¥6,300.
Based off the name, this may be a port of the like-named PlayStation 2 title from 2007. As a bonus item, Kadokawa will include Tobidase! Trouble Hanafuda Douchuuki EX2, presumably a new version of a PSP game that was included with the PS2 version's first print edition.
We're still waiting for further details and confirmation.
