When Ace Attorney 5—now known in the west as Ace Attorney: Dual Destinies—was announced for release outside of Japan, it was revealed it would be available as a digital title in the 3DS eShop only. According to Capcom USA senior vice president, Christian Svensson, that doesn't have to be the case.
Ace Attorney 5 producer Motohide Eshiro made some comments about the reasoning behind it, which you can read in a recent Polygon article. Basically it boils down to convenience, and preventing too much of a delay between the Japanese and American versions.
However, he also said if fans push hard enough for a physical release, Capcom will consider it. Svensson hopped on the Capcom forums to comment on this, and outline how you can help:
In the days after we announced AA5 for the West being digital only, and the requests of others for a physical release, we mobilized our US team to put together possible options that may address the concerns.
As a part of that process, Eshiro-san and I have met multiple times, including the morning where he gave the interview where he made the statement above. I was not quite ready to open the possibility to folks until we had a few more ducks in a row but Eschiro suggested he mention the potential in an an interview he was having that afternoon.
So, if you'd like to be heard, you can post on this thread (I'll leave it open), PM me on Capcom-Unity or hit up my twitter (@chrissvensson) as many folks already have. I need some additional ammo and these requests fit that need.
If things go well and demand is there, in a few weeks I may be able to present an option that puts the ball back in the fans' court (in "tennis" terms, not "of law" terms). I want to stress the word "may" so as to not misrepresent the situation or promise anything. We are trying. Again, timing and pricing would be at a disadvantage to the digital option as an assumption you should make.
On the [Ace Attorney Investigations 2] front, Eshiro is very much a man who could push make that happen so I'm glad whoever asked that question did so, but I've got nothing more I can add there. I feel the point above is valid.
Whether this comes to pass or not, Ace Attorney: Dual Destinies is set for a fall release in the west.
