Professor Layton's final mystery may have already started in other regions, but the release date for Professor Layton and the Azran Legacy was just confirmed for the U.S.

In addition to revealing the Feb. 28, 2014 release date, Nintendo dropped a brand-new story trailer for the latest as last Professor Layton title. Spanning both trilogies, Azran Legacy features more puzzle-solving mystery with your favorite detecting duo as they try to solve the fate of a lost people.

Layton's old world sensibilities are joined by some Atlantis-esque intrigue in the trailer above, and the upcoming 3DS title will bring the Professor's story to what we can only hope will be a spectacular close. The journey will span the globe, and introduce a wealth of new characters to the franchise. There'll even be some fantastic new animated scenes, all brought to life in glorious 3D (if you have it turned on).

While Professor Layton will be back again in the team-up game with Phoenix Wright: Ace Attorney, Azran Legacy is the final step in the franchise proper. Look for it early next year.
