Capcom announced Ace Attorney 6 (Gyakuten Saiban 6) at the beginning of September, and then it pretty much fell silent about the upcoming 3DS exclusive coming next year. Producer Motohide Eshiro briefly talked about it on 4Gamer.
According to Eshiro-san development is proceeding smoothly, and Capcom is going to provide a steady flow of new information on the game next year.
Personally, I hope that we’ll see this game come west in a reasonably quick time frame. I’d also like to see Capcom completely overhaul the localization and remove the silly westernization that plagued the series since its inception, but I’m afraid that will remain just a pipe dream.
