I could speak about this for hours, whether characters are going to appear on a tv show or movie is questionable at the moment, but I have theories.
Blade, Ghost Rider, Moon Knight, and Punisher will all show up in the future. We already had that name drop like
Alpha mentioned. Marvel Knights, and Defenders/Heroes for Hire. These teams seem to be aligning at the moment.
It could lead to some cameos from Cumberbatch onto Netflix perhaps? If not then I hope he can spin off into a magical side of the MCU, possibly starting a Phase 4 Midnight Sons event. He won't stick around the Avengers long after Infinity War, probably going off being all mysterious as usual. Since Marvel has the rights to Blade and Ghost Rider it would make sense to use them with Strange in a big event movie.
We know Daredevil, Jessica Jones, Luke Cage, and Iron Fist will be in Defenders at the very least, but I figure they might have a little company. Many might not know of Nighthawk, but he was a lesser known Defender. Season Two of Daredevil is being mentioned now. Thinking on how Dc has introduced heroes on other characters shows, I am curious if Marvel might cameo someone of importance there. Someone besides Electra I mean. Ghost Rider is a fairly easy character to do fx for if you use it in brief spurts. He looked good in Spirit of Vengeance, despite it being a shit movie overall. He needs to be done justice, but he doesn't fit the Defenders really. Well, if he was in the fucking Champions I guess he could be in Defenders...
Moon Knight doesn't need a huge budget, he does have his various vehicles, but the less he uses those the better. I guess if they did use Moon Knight in the MCU they could spin off a Secret Avengers movie, but I wonder how the general population would take to another Avengers movie? More of the same maybe? Blade has been done perfect. They can follow that formula and branch out into horror if they play their cards right, which I'm sure are perfectly stacked up until 2025.
With Daredevil they broke into the adult market and actually succeeded. Punisher is the easiest one they can bring into the fold. None of these characters should be wasted on Agents of Shield, even though I like that show, especially after the epic season finale. I would like Moon Knight on Netflix most of all.
So in the grand scheme of things, I would be content with cameos on Netflix for the time being. Maybe big movie type events on Netflix can handle some of these characters that really need a more mature audience. To be fair, all of Marvel's characters can be sanitized down to a PG13.
It should also be mentioned that all of these characters have interacted together numerous times. If Defenders has a few heroes, Defenders 2 (if there is such a thing) might have even more. Seems like they are going more street level though. At least until Strange gets his flick I guess.
The hardest part of Moon Knight is convincing people he isn't a Batman rip off.
That might do it.
