It is looking likely that a port of Professor Layton vs. Phoenix Wright: Ace Attorney is currently in development as the achievement list for the game has found its way onto Steam. The joint collaboration between Capcom and Level-5 originally came to the Nintendo 3DS in the west in 2014 and was well-received by critics. Level-5 and Capcom have not announced a new port at present.
Thanks to Greatsong1 for sending in the news tip!

Gosh this better be fake they’ve already ruined Yo-Kai Watch and the NintendoDS Remake..
well too bad because level 5 ceo gonna use ai to (upscale and stuff)
Who would publish this, level 5 or Capcom?
If the Steam achievement list is real, that’s a pretty strong hint that a port is on the way. Professor Layton vs. Phoenix Wright was one of the more unique crossover games on the 3DS, and it would be great to see it reach a wider audience. The mix of puzzles, courtroom battles, and story worked surprisingly well, so it definitely deserves another chance. I’m just waiting for an official announcement from Level-5 or Capcom before getting too excited. Until then, I guess I’ll keep myself entertained with a few games at a houseofjackcasinoau.com casino.
