*Western games, i know it's just not you but generalising 3rd parties to just western developers is irksome, especially in this case since Japanese support for the Switch is a different matter.
But yeah, kind of a no-brainer, Reggie didn't really need to state this
This is true for Japanese third party games as well for the most part. Though the generalisation is the impication that all/most of them ignore Switch. That's not the case.
What I'm refering to are announcements of Japanese games that have the PS4 and/or Xbox and PC logo on the bottom, but not the Switch logo. And that so far has been the rule rather than the exception. And while I do think it's a bit too soon to see an indication of exactly how common this will be, I don't expect it to change much.
Anyway, Reggie can say that, but they didn't create a platform where this is as easy as developers would have wanted.
The first you talk about i addressed in another reply, but it's certainly not as if i'm ignoring or not seeing this, i just think it's a matter of time, while with western support we pretty much know what games we're going to get, or lack thereof.
For the highlighted part though, evaluating the Switch's success in Japan and pretty much WW, i can't see Japan ignoring the Switch. Of course, Japan does have some big-scale projects and games that are running off the back of stronger hardware, but i can see some developers either making the effort to port it or making games tailor-made for it, or a multiplat game covering PS4/Switch. This isn't even mentioning that Switch will fill in the gap left by handhelds, which of course is very popular in Japan, and the 3DS and Vita over their lifetime have gotten many games from Japanese 3rd parties. No doubt will those developers move over to Switch.
