English for me.. it's an AES game so Language is dependant on what kind of system you have (or can boot if you have a Debug BIOS). My console is set to boot in Japanese Developer Mode by default, so I'm covered for blood and Engrish. I'd just like to have a manual I can read.
Also, I liked the Insert Art on the English SS5 more.. not that I've seen any confirmed art for this one though.
