I bet if The Witcher 3 was targeted with Switch in mind it will take longer than a year. The Witcher 3 on Switch was a port rather then using the same assets and same code. They have to almost modified the entire assets to look like 7th gen games.
Not necessarily. Switch ports often have another studio scaling it back even if launching around the same time.
Switch ports technically use the same engine and assets as well. Just better optimized for Switch.
Recently we've seen that with most recent Wolfenstein, MK 11 and its happening with the Doom Eternal.
