Its pretty clear that the Russo Brothers are literally born to direct MCU films. They just get comics. They made the 4 best, funnest and highest grossing MCU films…
Captain America: The Winter Soldier (2014)
Captain America: Civil War (2016)
Avengers: Infinity War (2018)
Avengers: Endgame (2019)
Their MCU films are all S tier but everything else they’ve made so far has been mediocre at best (save for the episodes of Community they directed which are also S tier, but as far as movies go, nothing synced for them like the MCU).
Its also clear that Disney needs them back. Its actually very hard to direct a fantastic comic book film. Its rare to make one, much less four bangers in a row.
If there is anyone that can bring afloat the sinking ship that is the post Endgame MCU, its the Russos.
So that they will be back to the MCU is an inevitability. The question is just how long it will take for the announcement to happen.
My wager is on under 9 months but I wouldnt be surprised it happens as soon as this July at Comic con. Who wants to take the over/under on 9 months?
