Unfortunately, for those who were hoping to get additional Marvel content besides WandaVision in 2020. It appears Black Widow will be delayed once again, pushing it to May 5, 2021 from its current November 6, 2020 date.
This will be the third delay for this movie due to Covid-19 which makes the release date nearly an entire year later than originally slated.
As for your MCU fix. Well you will have to be satisfied with WandaVision releasing later this year on Disney+
With Black Widow being moved that means both Shang-Chi and Eternals have also been delayed.
Eternals will now release November 5, 2021
Shang-Chi and the Legend of the Ten Rings will release July 9, 2021
