But it's not really true from that perspective either. FFXV team is tinkering with Switch, FFXIV team is actively developing on Switch, Omega Force and Gust have gone full Switch multiplat support, NIS has pledged to Switch support after D5C success, Nagoshi/Yakuza Studio plans to make Switch games, Tokyo RPG Factory, PSO2 is coming to Switch, Arc Sys fighting team is now on Switch multiplat, Hamster brought Arcade Archives, Tales is coming, 5pb Science VN, Tozai Spelunker, GalGun, Touhou spinoffs, etc. There is a good degree of expanded developer interest here despite Japan's general slowness to transition to new platforms and that's just going to grow as we go forward.
I'm not sure either of the bolded is true, and there's a very good chance the FFXV doesn't produce anything for Switch.
Regista (a company that seemingly makes only VN on PS platforms and PC, like Root Double) just announced they've been approved as Switch devs. Currently working on ports and new titles.

I guess Exile Election is one of the game Anihawk was talking about.
EDIT:
One, I'll say again that I think you are now shifting your arguments since the "Switch isn't getting any 3rd party games" one is being proven false.
Second, I would argue that you are really really overstating the "damage" from something like Inazuma Eleven going multi platform when you are essentially ignoring other franchises and heck entire publishers now developing for a Nintendo platform for the first time ever.
If Switch is retaining 3DS support AND getting a decent amount of Vita and PS4 franchises in addition to its own combined first party output, I fail to see how that equals anything else other than extremely healthy sales in Japan.
How many NIS/Gust/Omega Force/Blazblue games does it take to make up the lost software sales of something like DQXI being multiplatform? Will it actually balance out?
