Square Enix Asia just announced a physical release that brings both Final Fantasy VII and Final Fantasy VIII Remastered together in a single package. When Final Fantasy VIII Remastered was announced at E3 2019, certain retailers had a listing for a PS4 physical release but nothing materialized out of that so far. Today, Square Enix Asia announced a Nintendo Switch physical release that has not only Final Fantasy VIII Remastered but also Final Fantasy VII.
The Twin Pack is set to release this year in Asia including English and Japanese support. An international release has not been announced as of this writing. It is also worth noting that while the games are available on multiple platforms, Square Enix Asia has been doing Nintendo Switch only physical releases like World of Final Fantasy Maxima and even the recently announced Dragon Quest collection that brings three digital only games to cartridge.
Final Fantasy VII and Final Fantasy VIII Remastered are available on PS4, Xbox One, Nintendo Switch, and PC with the former also being available on iOS and Android.
