As a result of the ongoing coronavirus (COVID-19) pandemic, Marvel Studios and Disney have delayed the release of several Marvel Cinematic Universe films. This is the result of having to once again delay Black Widow, which has created a domino effect for the various films in Marvel Studios' Phase Four.

Here's the new timeline for Marvel Studios' Phase Four following the delay of Black Widow.

The Falcon and The Winter SoldierLoki and What If...? are all set to premiere in 2021. The Falcon and The Winter Soldier, which was originally slated to release this fall, stars Sebastian Stan and Anthony Mackie in its titular roles as they team up to take on Daniel Brühl, who reprises his role as Helmut Zemo from Civil War. The series will likely air its six episodes in early 2021.

Finally, What If...? is a ten-episode animated anthology series scheduled for mid-2021, though the exact date is unknown at this time. The series, which is inspired by the comics series of the same name, will look at what might have happened if events in the MCU timeline occured differently. Marvel Studios is already working on What If...? Season 2.

It's unclear at this time if any of these three series will be delayed as a result of the recent schedule shuffle.
