Resident Evil 4 has gotten a standalone physical release on Switch, but Resident Evil 5 and 6 are digital-only affairs. At least, that's how things have been since those titles originally hit Switch, but now it seems that both games have standalone physical releases on the way.
Aussie retailer Mighty Ape has added listings for physical versions of Resident Evil 5 and 6 to their website. The site shows a March 27th, 2020 release for both games, and even includes the cover art seen above. Nothing's official until Capcom makes the announcement, but it certainly seems like this is the real deal.
