That's why Sony is trying to get a "PSN Imports" part of the Playstation Store. That way developers don't need to set up packaging for retail, port the code to a specific region, or hire any fleshed out localization team.
All they would have to do is get a couple people to translate the text, and put the file up for download. I actually think a game like Yakuza 3 would play pretty awesome like that.
