Besides the announcement of Ant-Man and common sense of Avengers 3, I feel there will be 3 other films in Phase 3: Inhumans, Doctor Strange, and Black Panther. Along with the Netflix series, all of these will have the theme of REDEMPTION.
Doctor Strange:
This will pretty much be the usual origin film there. I do believe that like the animated Doctor Strange movie, he will not be able to save someone through medicine. Which then all leads up to the end of the film where he does save the world. Another aspect of REDEMPTION. I would think that for the first film, Marvel would just use Baron Mondo with maybe Dormammu being behind the scenes. Also, I feel that Eye of Agamotto will be an Infinity Gem, probably The Soul Gem.
Inhumans:
Just like Doctor Strange, it will be an origin film or a film about Inhumans living among us. I could see the "Inhumanity" story line get adapted. The Terrigan Mists could be an extension of the Mind Gem. Black Bolt will be removed as king, but in the end return as king.
Black Panther:
Another origin film like most of Phase 3. T'Challa father will die in battle, while T'Challa is away after a fight with his father. Typical story line of being the son that never lived up to his hype/destiny. T'Challa grows to become the hero he is destined to become at the end. I guess have a modern update to Klaw here.
I could also see Ka-Zar being a film that also gets made into a film. I would see that the whole film making you feel like this is in the past until the last five minutes where you realize that its in the present time. I also can see a "Lost World" type story, where adventurers discover the Savage Land. If this movie happens, I could see the Reality Gem being part of it.
Avengers 3:
Guardians, Avengers with background cameos by Black Panther and Doctor Strange and The Defenders vs. Thanos. After events of Avengers: Age of Ultron, society and the government distrusted and are hunting the Avengers. Thanos comes to Earth, with the Infinity Gauntlet and Gems. Earth is the battleground, and in the end Thanos is defeated, reality is restored and the Avengers are once again respected.
Netflix series, all of them have the common thread of street level heroes and REDEMPTION, with each heroes having some sort of event that they need to overcome.
