Fear not, they will likely be adding Japanese voice acting to the PS3 and maybe PC release.

Full interview here http://www.videogamer.com/xbox360/the_last_remnant/preview-1384.htmlVideoGamer.com: One of the things a lot of the fans have always wanted from JRPGs is the original Japanese dialogue with English subtitles because they feel it's more authentic but that never seems to be an option. Why is that, and do you think that games on Blu-ray might allow that because of the increased capacity?
Isogawa-san: Because this is the 360 version and it's just a DVD we didn't end up with enough room on the DVD to have two languages worth of voice. There's a lot of voice in this game. It would be cool if we can do that for a Blu-ray release. We'll see!
