As an aside—this is probably a pipe dream at this point, but if that KH Disney+ series still miraculously exists, it most likely would be shown at the 2 hour Studio Showcase at 6:30pm ET the same day. The description says:
“Join Disney Studios for an all-star look at what’s coming up in theaters and on Disney+ from Disney’s iconic Walt Disney Animation Studios and Pixar Animation Studios, as well as its namesake motion picture group behind such recent Disney hits as Cruella, Jungle Cruise, and Chip ’N Dale: Rescue Rangers.“
…though I’m pretty sure the rumors were that Square was developing the series in-house, and there’s no “third party studio” showcase listed anywhere, so. *shrug*
