Lately, there’s been a story going around the Internet about how Ace Attorney Investigations 2 isn’t going to be seeing a U.S. release, based on comments made by Capcom’s Christian Svensson in a recent “Ask Capcom” video Q&A.
However, Svensson hinted that AAI2 might get a possible release on a different platform in the future as stated here;
I'll be a little more clear.
The costs of localization are higher than the forecasted return. And no, it wouldn't sell more than Okamiden (which has already sold more than the first Investigations).
Could this content show up on some other platform somewhere down the line? Possibly, but there's nothing on that front for me to talk about. I realize there are fans who would like to have this and I'll be sure to explore ways that could happen viably in the future with our strategy and R&D teams but no promises.
