A Dmitri Bukharin Crimson Dynamo would be awesome, or maybe even a huge BAF Anton Vanko Dynamo. Or both??? Maybe I'm asking for too much, but I love me some Dynamo and I would be so hyped to see those figures.
Ursa Major would also be a pretty cool BAF, but I'm afraid Hasbro will pass on him since... well, the figure would literally just be a large bear. It would require a lot of unique tooling for a character that very few non-comic fans would be interested in. Don't get me wrong, bears are awesome and so is Ursa Major, I would love to see that figure. But I kinda doubt it's gonna happen? Hopefully they'll prove me wrong.
I definitely expect to see another comic Black Widow figure. Why are some people here claiming they don't include comic versions of the main character in movie waves? We got a comic Strange in the Doctor Strange movie wave and a comic Iron Man in the Infinity War movie wave. I am expecting to see a white repaint of the 90's Widow we got in the Toybiz-style vintage wave. It would be a very obvious repaint that would be guaranteed to make a lot of money. It's not exactly a figure I would be super excited about, but if they can save money on a certified cash maker and use the leftover money to make more original characters like Dynamo, I definitely think it's worth it.
A Titanium Man would be another character I'd love to see. I know he hardly has anything to do with Black Widow, but we probably won't get another Iron Man wave for quite some time, and he DID fight Dynamo once, so a Titanium Man wouldn't be too far-fetched imo. And it would just be such a sick looking figure. He could be another potential BAF, depending on how large they make him.
And a totally classic Heinrich Zemo to complement the Helmut Zemo we got in 2014? YES PLEASE! Or just an updated Helmut Zemo with his shoulder fur, that wouldn't be too bad either.
