All right! This is the best news I've heard in a while. Digital-only isn't my favorite scenario, but I'll take what I can get.
Regarding the trailer - I'm glad to see they featured some dialog with subtitles. With the Western Yakuza 4 trailers, it almost seemed like they were trying to hide the fact that the game is subtitled. This is the proper way to go - just do the trailer like a foreign film. At this point there's plenty of gamers who can appreciate a subtitled game rather than a badly dubbed one.
