Wait, why would Black Widow be Scarlet's last movie in the MCU? I assume they want to make sequels out of Black Widow, right?

^Well they killed her off for a start and there are in reality quite few gaps in her timeline post Iron Man 2. So they don’t have much to work with. Not to say sequels/prequels won’t happen it’s just that I wouldn’t bet on it.

I'm excited for the appearance of Hawkeye and Winter Soldier, and I wanna see what exactly the Red Room is like

I do hope they explain what happened to the red room, presuming it is closed now.

I also wondering if one of the purposes to this movie is the introduction of Taskmaster.

Introducing the taskmaster and also pay tribute to black widow.

@MarvelSharky Did someone say Taskmaster?

I hope this film does feature Hawkeye in some way, not necessarily because I care about Budapest, but more so because I want a Hawkeye vs Taskmaster archery and close combat duel.

Winter Soldier is honestly not as necessary. Plus he was more so HYDRA’s agent than the KGB’s or Russia’s.

That sounds like an interesting fight. I’d watch that.
