GOING FORWARD.
The beginning of the end of the Marvel Cinematic Universe, setting in motion the events that'll lead to the Infinity War. It's much darker than the previous movie, and it has serious consequences, including mass casualties that lead to the creation of the Superhero Registration Act. Captain America reforms the Avengers with Black Widow, Hawkeye, Quicksilver and Scarlet Witch, while Iron Man agrees to support the Registration. Thor returns to Asgard and the Hulk goes on the run due to the several people he accidentally killed. Spider-Man is introduced in the after-credits scene.
ANT-MAN.
Self-contained, though it presents the new landscape of the MCU in which superheroes are public enemies and blamed for the massacre perpetrated by Ultron. Henry Gyrich is introduced as a CIA agent acquiring weapons from Pym Technologies. He is played by Martin Dovanan and will return for the Civil War.
CAPTAIN AMERICA: CIVIL WAR.
The tipping point of the MCU. Captain America and Iron Man on opposite ends of the Superhero Registration Act, both trying to prevent HYDRA from attacking Wakanda and leading to an international conflict, while Captain America is also trying to protect Bucky from Iron Man. It's a big movie with a lot of players. Neither Captain America nor Iron Man will be villains, that role is reserved to Baron Zemo and Gyrich, but they'll be on opposite sides and come to blows. Spider-Man has a minor role, acting as an audience POV throughout the conflict. Captain America will die, which causes Iron Man to blame himself and retire.
DOCTOR STRANGE.
Self-contained, though it introduces Doctor Strange, who will be a pivotal character in the Infinity War, and the Reality Gem. Doctor Strange's powers are explained on vaguely scientific terms related to quantum physics and parallel Universes. The villain is Baron Mordo and Dormammu.
GUARDIANS OF THE GALAXY 2.
One of the biggest lead-ins to the Infinity War, with the introduction of Adam Warlock and the Soul Gem. The Universal Church of Truth will be present, though they'll be connected to Thanos. Nova Corps, Ravagers and Nebula also expected to return. From what I've heard, it's a "chase the McGuffin" movie with all these separated groups trying to find Warlock's cocoon.
Not much is known, as Sony is developing it. It won't be an origin story, Peter's parents' aren't involved, Peter will be in high school and Gwen Stacy and the Green Goblin won't be done at first. Spider-Man is a "people's hero" that looks after the common man, and has been active for a while, but will face his first true supervillain in the movie. Mary-Jane Watson will be in it as Peter's childhood friend and soon-to-become romantic interest.
THOR: RAGNAROK.
The Ragnarok is caused by Loki to settle his debt with Thanos, which is part of Loki's larger masterplan. Thor is caught in the crossfire. It's massive, and Surtur will be present. Several characters will die, and Thor will end the movie trapped in Hel.
BLACK PANTHER.
Self-contained. T'Challa will be introduced during the Civil War, but become the Black Panther here, dealing with the political tensions between his country and the rest of the world over Vibranium mines and the looming threat of HYDRA. Killmonger and Klaw will be the villains, more might be added.
AVENGERS: INFINITY WAR - PART 1.
Thanos begins collecting the Infinity Gems to assemble the Infinity Gauntlet and subjugate the Universe. With Captain America dead, Thor trapped and Iron Man in shambles, Doctor Strange assembles Spider-Man, Quicksilver, Scarlet Witch, Black Widow, Hawkeye and Black Panther to fight Thanos. As expected, they fail. Thanos, aided by Loki, causes a catastrophic event, but the arrival of Adam Warlock and the Guardians of the Galaxy allows them the heroes to survive.
CAPTAIN MARVEL.
Carol Danvers is being introduced in "Black Panther", and Thanos' actions lead to her developing cosmic powers. Her movie is about her accepting her role as a hero and being recruited to the Resistance against Thanos. I hear she'll have a "kinship" with Black Panther.
AVENGERS: INFINITY WAR - PART 2.
The final battle. Although this is subject to change, it's meant to be an all-out battle. Iron Man is brought out of exile, Thor is rescued and Captain America is briefly revived, as they rally all Marvel heroes, including the Netflix heroes and the TV show heroes, for a massive battle against Thanos. Loki's treachery will prove vital to Thanos' defeat, and I'm hearing it'll all culminate with Iron Man sacrificing himself to defeat Thanos, with Captain America also returning to the world of the dead once Thanos' is defeated.
INHUMANS
Self-contained. Basically, it's the Royal Family of Attilan dealing with the humans' looming discovery of their existence and the intrigue between Black Bolt and Maximus. Crystal is the central character.
GOING FORWARD.
Further movies will deal with the ramifications of a world without its cornerstone heroes, Captain America and Iron Man. Spider-Man's importance will only increase, as will Doctor Strange's. Bucky will become Captain America and might get his own movie if proven popular. Depending on the public's reaction to "Infinity War", they'll begin setting up another massive overarching storyline.
