Nintendo announced Ever Oasis, a new IP developed by Grezzo, during their Treehouse stream at E3 2016.
The title is part adventure – part city building sim which takes place in a desert like location. You play as the leader of an oasis, who goes out adventuring for resources to build up the oasis with buildings, such as shops which can develop and perpetuate the in-game economy.

As implied by the fact sheet, there is no confirmed release date for Ever Oasis yet.
