John Hardin, Atlus PR guy, posted on a Yakuza 5 thread earlier this week in response to people complaining about SEGA using Atlus stratey and ignoring Europe. He basically said it's either this or things go back to the way they were before. Pretty much indicating this is all happening because of Atlus. I'll see if I can find the post, but theres been so many Yakuza threads on gaf recently, so no promises.
I guess Atlus just doesn't have the resources needed for a complete EU localization which is why they ever only do USA. Interesting snippets from a recent yakuza stream by SEGA and Gamesradar. I didn't capture these, @SSF1991 on Twitter did.
Certainly leaves many questions. SEGA Japan has spoke in their financial reports how they want to localize games again, yet it seems SEGA West doesn't want to localize games still? So now it's happening through Atlus instead?
Atlus is the best thing that's ever happened to SEGA in a long time, if that's the case, IMO.
