I have doubt because I don't want to waste $15, and Vita compatibility is a clusterfuck full of confusion and misinformation, especially involving Jeanne D'Arc & Gran Turismo PSP recently being on the Vita store for a week or two without actually being downloadable.
It's easy enough to press the home button and the start button at the same time to screen cap something on the Vita. ie: these screencaps I just took that would prove to someone they can buy Cladun x2 on the SEN store and download it directly to their Vita, with no PS3 needed, even though it's not listed on the actual Vita storefront anymore -
I'm not asking for much, just certainty.
