Every company goes through this question, but it does seem to be a focal point for Nintendo in particular.
I'm of the mindset as a fan where as long as I get the usual games that I'm expecting and hoping for (Zelda, Fire Emblem, 3D Mario, Xenoblade, Smash Bros., etc.) and they're all as good as I've come to expect from those franchises, then they can do whatever else they want on the side. So, I guess I have nothing to worry about because none of those franchises are in danger of going on hiatus or dead like F-Zero or Star Fox... Well, Xenoblade maybe, but between 2, Torna, and the Definitive Editoin of 1, I've got nothing to worry about for now.
Furthermore, it has been this creative freedom and exploration that has led to some of Nintendo's biggest sellers and A tier franchises right now. (Animal Crossing, Splatoon, Smash Bros.) Yeah, it may lead to a few stinkers or flops every once and a while. But when they manage to find a hit, it's not just a hit, it's a Home Run!
