People conflating the importance to Nintendo of a extremely niche game like TW101, with Bayo2/3 is wild. I mean anything can happen, but they aren't even close to the same importance to Nintendo.
Bayo is now Nintendo's flagship action game series for their system that they know people will buy the system for. I am guessing Astral Chain is also their hope to convince the character action game crowd to see that the switch is where some of these games will be that aren't playable anywhere else, pushing hardware sales. I wouldn't be surprised if they are also hoping the sales of these games convinces Capcom to start to put the DMC series on the system (current games, not super old ports)
TW101 is just a tiny niche game that they don't really care much about as it doesn't affect them really at all. People aren't going to go out and buy a switch just to play a remaster of a extremely niche game, so it going to PS4/Steam isn't really losing them hardware sales. And lets be honest, the asthetics of the game already place it firmly more in the switch demographic than any other ecosystem. I also bet that neither Nintendo or Platinum expected the TW101 kickstarter to blow up like it did. If they did think it would, they probably wouldn't have let this happen.
