The great thing is that many of these people probably aren’t too far away from their debut, either on D+ or the movies :)

Anything and everything is on the drawing board. It's only a matter of when.

One thing that I think that people forget is that Feige is probably not much of a Bendis fan. That's not to say that he dislikes the man or his writing, but rather that his tastes were set long before Bendis started writing for Marvel.

Fans whose main impression of Marvel is from the year 2000 onward probably weigh the importance of various characters far differently than guys like Feige. Marvel comics put a lot of effort, following the X-men movie, into adapting their own characters into versions that would be easily translated into films, but the guys making the films like Feige are more interested in doing their own adaptations of the characters and concepts that they already liked.

Hence, I don't think that it's all that surprising that characters like Spider-woman (a minor character that happened to be a Bendis favorite), Sentry, Red Hulk and the like haven't been a priority so far. Most of the others here are/were tied up in rights issues that make them less attractive to use.

Of the newer stuff from Marvel Comics, it's not surprising that the cinema side has been attracted to stuff that isn't already represented on screen.

Hopefully Norman will be referenced or even make an appearance in Spider-Man 3, setting up the Green Goblin in the future.

I hope use Kang the Conqueror as the main antagonist in a Young Avengers movie/D+ show.

Captain Britain should appear in Excalibur - a spinoff of X-Men.

Beta Ray Bill is the only one on this list I agree with. The fact that we got through a Thor trilogy without him is surprising especially since they already used Surtur in Ragnarok
