I kinda doubt they wouldn’t, to be honest. Both the Wii and Wii U had one generation of backwards-compatibility. The Switch didn’t probably due to a combination of the form factor and the fact that nobody had Wii U games anyways. Also, the PS5 and Series X/S both have backwards-compatibility. There are issues with the classic console lifecycle, but this one has been solved for awhile now.
