Capcom can't be helped and the same will probably continue to hold true to varying degrees for the other big publishers. Square-Enix has at least committed as much as keeping the Octopath Traveler studio on Switch games and their Tokyo RPG factory is multiplat anyway; chances are that they start to dump Kingdom Hearts ports on Switch too. Dragon Quest XII should be a given. Atlus has stuck with the 3DS for a long time, but they obviously have to move on.
Overall, I don't think these publishers are important enough to really harm Switch with their lack of support, because the smaller publishers have already included Switch in their game development. Support will improve over time, but third parties on the whole won't make use of the full potential that's there.
1. I refer you back to the post of mine that you quoted. The 3DS sold another 11m units with next to nothing left. That's close to half of its lifetime sales.
2. I named Ring Fit Adventure as an example, so why do you even ask?
But Ring Fit is a fluke, there is not many jokers like this.

LET'S FACE THIS FACT : The Switch is the last physical video game system of the history who has a chance to beat PS2's sales.
