IGN. It sounds like Kevin and Marvel have enough films in the works to keep fans happy for the next ten years.
CAPTAIN AMERICA 2: The film will be set in modern times but very well could have WWII flashback scenes. As writers Stephen McFeely and Christopher Markus have talked about including a few more WWII scenes in the sequel. Hydra is likely to be back with possible villains Baron von Strucker, Madame Hydra and Zemo. With Sebastian Stans' contract to be in bunch of Marvel films I expect we will see a transformation from Bucky to Winter Soldier. Zemo being a mantle villain it would be nice to see a mantle hero like Union Jack also involved with the sequel.
THOR 2: Not much known here as it was just confirmed the sequel is happening. Hopefully it will be more realm focused as there a bunch of villains and mythology to explore off-Midgard (Earth). Fellow Asgardians Balder and Valkyrie have yet to be introduced along with Dark Elves, Rock Trolls and other villainous creatures. The world of Thor is rich and might be the first step for Marvel to expand our concepts of the superhero genre.
BLACK WIDOW: David Hayter (X-Men, X2) wrote a Black Widow script and was aiming to direct when it was setup at Lionsgate but was eventually scrapped. It's unknown where the project is at the moment but there is more talk of this spin-off than the others. Johansson is game as mentioned at last year's Comic-Con.
HAWKEYE: There have been plans for a Hawkeye film for years and now that Jeremy Renner is in place for the role they can finally move forward with it. I'm not sure if there was ever a script developed but I wouldn't be shocked. Personally I'd rather see a Widow/Hawkeye team-up film as they'd work better as team than in solo projects.
S.H.I.E.L.D: This one has been teased since we first got a glimpse of Nick Fury in Iron Man. It seemed that with a script by Andrew W. Marlowe (Air Force One) kicking around for years it would go soon. While it's expected Samuel L. Jackson, Clark Gregg and Cobie Smulders will be in this it's unknown if other currently cast Marvel heroes will also appear.
IRON FIST: Unlike Strange and Panther which have been in development for almost the same amount of time they actually have someone in mind for the lead. Ray Park had been attached and is still interested in the role. He's currently getting ready to return as Snake Eyes in G.I. Joe 2. Marvel recently set Rich Wilkes (xXx) to work on the film's script and is likely to be based on The Immortal run of the character being more of a martial arts film.
DOCTOR STRANGE: The only real news on this front is that Marvel has hired Thomas Donnelly and Joshua Oppenheimer to start writing the script. The two are responsible for the Conan reboot and likely involved with it's sequel. While Patrick Dempsey (Scream 3, Transformers 3) has been campaigning to play mystical hero.
BLACK PANTHER: Wesley Snipes had been in talks with Marvel for the role but with his troubles it's unlikely that will happen. Actors like Michael Jai White (Spawn, Dark Knight), Adewale Akinnuoye-Agbaje (G.I. Joe, The Thing) and Idris Elba (Thor, Ghost Rider 2) have been in the mix for T'Challa. Mark Bailey is currently writing the script.
ANT-MAN: This one wasn't called out by Kevin but it's assumed with a script and director in place it will be down the production line sooner than later. There was also zero talk of Luke Cage, War Machine or Sub-Mariner.
UKNOWN-COSMIC FILM: There hasn't been a full on confirmation of which one of the cosmic epics Marvel could be working on. I would love to think this is a Silver Surfer movie but it's more than likely Killraven or World War Hulk.
