Pokemon Go has taken over my city, I've never seen anything like this.

Something that blows up as huge and fast as this is bound to deflate at an equally impressive rate, that's just how trends work, the entertainment nomads will soon find new pastures and move to the next "it" thing. Major kudos for creating a global phenomenon though, it's good to see some real revenue streams flowing Nintendo's way again!

Even fads still last quite a while. Candy Crush, Clash of Clans, and Angry Birds are still getting considerable numbers of downloads today. 

Wii Sports/Fit were popular for several years too. 

Nintendo is just at the beginning of this gravy train. 

True, some last longer, but the majority drops off while a part of the customers remain. The bar for installing and uninstalling mobile apps that are either really cheap or even free will ensure that it's a much more volatile and fast-paced market than console or handheld console markets. But this is well known.

I guess we'll see in a few months what the retention rates look like. I really agree with you last bit though; mobile/tablet is where they money is at an Nintendo can do better than mostly anyone else in this space of gaming if they do it right.
