Nintendo need to target a slightly more mature audience.
The Tablets and free 2 play games too away alot of the crowd nintendo used to target and I doubt they will ever get that back. The solution is to get in the game, and aim for a more mature crowd.
Get the teens and early 20s that want to play action/open world rpgs, and first/3rd person shooters.
A more serious and bigger budget Splatoon for NX, would be a start.
Getting 3rd party back would help as well. Mario Open world RPG? make it happend nintendo.
*edit:
Imagine a witcher style Mario RPG ? :D would be epic.
A Call of Duty styled Splatoon.
Time for nintendo to take inspiration from whats on the market and selling well, that people love.
Just pour abit of nintendo style flavor into it (the characters they own) and that should be a win.
