We’ve been hearing about Nintendo’s plans to make mobile games for the better part of 2015, but tomorrow we’ll finally learn some concrete details about Nintendo’s first official mobile product.

Nintendo CEO Tatsumi Kimishima said today that his company “will talk about details tomorrow,” referring to Nintendo’s first smartphone game. Interestingly, Nintendo has managed to keep pretty much all of the details of its first mobile game under wraps, which is pretty rare in the mobile industry where seemingly just about everything leaks before its official announcement.

Nintendo is one of the biggest names in gaming around, not only because it’s been around for a very long time, but also because it’s got some of the most recognizable characters around. However, Nintendo’s latest console effort — the Wii U — hasn't done quite as well as Microsoft and Sony’s boxes. Now Nintendo will finally enter the mobile space, and while it remains to be seen exactly what the company has planned, the games — which will be made in partnership with mobile game maker DeNA — could do well for Nintendo if they’re well made.

Nintendo has said that it plans to release a total of 5 mobile games through 2017.
