Persona 2: Eternal Punishment will be downloadable from the PlayStation Store on Vita and PSP starting March 12, thus making it possible to collect the whole Persona series from the comfort of your Vita.
The PSOne Classic was released in February, intended for use on PS3, PSP, and Vita, but mysteriously only playable on PS3. That was later patched to work on Vita and PSP, but only when transferred from PS3. Now, it is finally being added to the store on those platforms.
