Picross 3D: Round 2 was released in Japan last October, and according to a recent classification on USK, the German Entertainment Software Self-Regulation Body, a Western release might not be too far away.
The submission was made on the 18th November 2015, but the document has only been made public recently.

The title supports 10 amiibo, Mario, Luigi, Bowser, Peach, Meta Knight, King Dedede, Toad, Yoshi, Link and Kirby.
Here’s an amiibo gameplay clip posted last year from the Japanese version by GameXplain:

Yes! Picross 3D is definitely one of my favorite Picross games, I can’t wait!
Same! It was so addicting!
