I'll give you a list Ed.
Love to see more from Atlus, maybe even get a Persona game on the Xbox one day.
Arc system Works, although they've seemed to have shunned the Xbox lately. Not even one little rumour about Chronophantasma for the Xbox.
Namco Bandai Games, if only for Tales.
Grasshopper Manufacture too. Speaking of, I wonder if that Lily Bergamo is actually a PS4 exclusive.
