From Nintendo’s press release:

Nintendo announced that its next two mobile apps would be based on the familiar and beloved Fire Emblem and Animal Crossing franchises. Nintendo plans to release both of these applications this fall.

And:

Nintendo confirmed that NX is scheduled to launch in March 2017. NX will not make an appearance at the upcoming E3 video game trade show in Los Angeles in June and will be unveiled later this year.

And:

The latest installment in this classic franchise is scheduled to launch simultaneously for both Wii U and NX, and both versions of the game have been in development in tandem. Because developers need more time to polish the game, it will launch in 2017, but it will be the focus of Nintendo’s presence at E3.

Finally, Nintendo of America tweeted this early this morning:

More #Nintendo apps are coming to smart devices, including Fire Emblem and Animal Crossing!

Can’t wait. Fingers crossed that in-app purchases don’t ruin some treasured game franchises.
