For not Japan; it already came to 3DS in Japan
Ace Attorney 123: Wright Selection came out in Japan. It's coming to the 3DS eShop elsewhere this winter. Wright Selection includes Ace Attorney, Justice for All, and Trials and Tribulations, all gussied up with stereoscopic 3D.
Capcom had it on hand at E3 so I went and played through the beginning of each game. Nothing to report than it looks pretty good and I, as usual, turned the 3D off pretty quick.
