I have two quick points. I may be completely wrong. But what if :
1) Nintendo can not comment on mobile games at this time, but there is clearly mobile games with Dena on the list of software developers. If there is mobile games, there is multi touch screen. If there is multi touch screen and it has apps. Whose app store is it using, Google, Amazon, Windows, or ...iOS? Nintendo won't have its own app store. It would be a modified version of one these. Those agreements could be being kept secret for now.
2) I am starting to think that this Switch CAN run graphic intensive games like Red Dead 2, and Doom. But only if the SCD is true. What if that rumor about a SCD is true. While it would fragment the market some, but that could be a "hardcore gamer" package for $399. Really smart move if true.
