So far, I guess you can say that the models have been ripped from the game. They're just not currently useable in any animating programs. If you can help, here's a Google Drive folder containing MOD, MRL, and TEX files. There are some being uploaded right now. Invertigo at Court-Records forums had written a program that converts Dual Destinies iOS' TEX files to PNG, but this program doesn't appear to work with the 3DS version's TEX files.
