It will be interesting to see where Sony and Microsoft go with their next consoles, and when that will even be. Lets hope that when/if those guys put out a new console, it will also use carts like the Switch.
I mean, if it does come out in March of 2017, you've got Nintendo's cart based console competing with the PS4 and Xbone, which still use discs. I wonder if that will affect how much 3rd party support the Switch will get for the first few years it's out.
Though maybe it's not that hard to transfer stuff over from disc to cart nowadays.
