There is a contract of exclusivity for the PS5 release. Yoshi stated they were unconcerned with optimizing for a PC port at the moment and he seems pretty sure most people's PCs cannot handle the game as it is meant to be played. This does not mean never and the language he used did hint that it was not out of the question, just not a priority or being simultaneously worked on so they could focus on hitting the PS5 release with the original vision intact. However I would be surprised as heck if after that exclusivity period ended an announcement that the game was being released on PC wouldn't be shortly after.
