I still have the impression that some games that were planed to release on the Wii U were postponed to release on the Switch. Also I think that some games of last year (Zelda, Mario Odyssey) were finished developed some time before release day so that they would be released on the fitting moment.
Consequently in my opinion the Zelda team is already working on the new Zelda since around 1.5 years.
