According to some info I learned, Namco X Capcom will get a release in the US sometime around September 28th. It'll pretty much be a complete port of the Jap version except the only thing to be translated is the text. It probably won't have ANY voice acting at all.
Of course I don't know how right I am at the moment, so lets just wait until the day arrives to find out.
From what I heard people who polayed the Tales games (Tales of Symphonia, Phantasia, etc) would get uses to the play style of this game as you can control them in real time during battles, you can switch control of a character by pressing a button, and you can execute special attacks with button combonations.
