It feels that way, based on this bit from GeekTyrant about WANDAVISION: “WandaVision kicks off on Disney+ on January 15, 2021 and it will roll right into the final Friday before The Falcon and The Winter Soldier premieres on March 19.” Nine episodes, by the way – but it’s the part about how they’ll be dropping new episodes every Friday, and presumably they have shows lined up for after F&TWS’s last episode.
I guess This Is The Way now, huh? THE MANDALORIAN worked out (probably better than it would have if all the episodes dropped at once), so the Mouse is going to regularly drop new content on Fridays and not fuss overmuch if that turns out to be the big viewing day. After all, they’re not selling advertising on Disney+. Or at least not yet.
PS: It’s odd how there’s no THE MANDALORIAN DVD. I have no theories as to why, mind you. I just find it generally odd.
