You know, we only ever got a PS1 and PS2-level Persona (I guess PSP Persona 3 would be closer to what a 3DS persona would look like). Now we're going to get a PS3 level Persona, that should be a nice jump. Even though they're not using the engine in Catherine, that's still a good indication of what is possible for the game to look like at full scale - and that still excites me.
And IF the game was on Vita or PS4 and moved, there is no reason why a version still can't come out for those platforms once this one is successful. It just means a longer wait.
Everybody wins in the end. Persona for everybody!
Except that weird dancing game. Fuck that shit.
