Huh, at 1:38 you can see the Super Mario World title screen also show "Super Mario Bros. 4". I legitimately have never seen that. Must have only been in a beta/marketing release.
That title screen was one of the founds in the 2020 Nintendo Gigaleak.
Fun fact, Super Mario World was developed at the same time as Mario 3. They even used Mario 3 assets in the early builds. They wanted to make 3 as a send off of the NES and World as a highlight of what the SNES could do.
