First party games Nintendo has announced and coming out
Xenoblade 3 (low budget, iterative sequel)
Splatoon 3 (iterative sequel)
BotW 2 (heavily delayed, was probably supposed to come out already, also an iterative sequel albeit one that will probably add a lot of content)
To my knowledge, that's it. This is not normal, especially at a time when Nintendo is massively ramping up their software development budget and you would expect more first party games to be announced. There's a ton of games still coming to the switch, but they're not being made by Nintendo. Nintendo doesn't make Pokemon for example.
