It seems to me that a Switch version is about extending the growth of the IP as a means to returning back to the main series on PS consoles.
There's no PS4 version, presumably because there's not a large enough audience left to migrate to PS5 for the future of the series.
There's no Xbox version because... Lols I guess. No reason to put their stuff on a competing system.
I doubt we'll see the mainline games move from PS and PC, at least not on any immediate timeframe I feel.
