Yeah this came up while I was browsing the Switch section. You can see in the upper left corner it's indeed there, and it shows Switch in the listing title, as opposed to other PS4 games. Note that this is an import listing for the NISA release since I don't think this was even announced for Japan.
This is oddly similar to this listing I saw before of Yumeutsutsu Re:Master which was similar but has since been fixed, but it is actually coming to Switch but only on the eShop for some reason.
Plus it IS NISA, so it would not be surprising at all for them to get a Switch port made if this was true.
Thoughts?
