According to VGC, several sources have suggested the Japanese publishing giant will hold a special event to mark the occasion. Super Mario Bros. originally hit Japanese stores in September 1985, shortly followed by North America.
In a follow-up story by sister site Eurogamer and confirmed by Japan-specialist site Gematsu, the list of games heading to Nintendo Switch include Nintendo 64 classic and speedrunning favourite Super Mario 64, the GameCube's flagship title Super Mario Sunshine, and the popular Wii entry Super Mario Galaxy.
Other titles seeing a Switch release could also include Super Mario 3D World, according to the reports, with a Super Mario All-Stars-style collection possibly on the cards.
This appears to be part of a grander Nintendo strategy for 2020. The publishing giant has already revealed an interactive new Lego Mario set, and the construction of a Super Nintendo World theme park at each of Universal's locations in Osaka, Hollywood, and Orlando is under way.
Despite 'most of the Nintendo back catalogue' seemingly being on the menu, The rumours are yet to be confirmed, with Nintendo expectedly refusing to comment on speculation.
With E3 now out of the question, it's unclear as to how Nintendo plan to announce any upcoming titles. We'll stay tuned for a possible Nintendo Direct reveal.
