So that means 2020 is officially going without any MCU material for the first time since 2009.
Sucks that we have to wait until Mid-January, but I get it from the Disney+ side. They have a lot going on through December with The Right Stuff finishing up, Mando going until December 18th and then Soul (along with a slew of other original movies and specials). Disney probably sees their December as having enough content and it’s not ideal to start a show at the end of the calendar year anyway, especially when the show is only a 6 episode mini-series.
Plus, they may run into an issue of having to wait a bit to release Falcon and the Winter Soldier because of Black Widow, so this at least fills a gap.
