-Thanos will be in Thor 2. He has to be. Even though Thanos was originally an Ironman villain the Infinity Gauntlet is in Asgaurd in the same vault as the Cosmic Cube. Thanos needs it and unless Loki escapes I don't see how he'd get it.
-As Far as Marvel movies go we know that Ironman 3, Captain America 2, Thor 2, and Wolverine 2 are all in the works.
-Avengers 2 is still in preproduction.
-Mark Ruffalo signed to play Bruce Banner/Hulk in 6 more films-that doesn't mean 6 Hulk movies.
-I'm just curious to see if they pull Spider-man into the Avengers 2 (he is one in the comics) but Sony still holds the film rights to Spiderman. The new cartoon (while horrible) is about Spiderman receiving training from shield to be the "Ultimate Spiderman" Perhaps that's how they tie him in. either way spiderman is too popular of a superhero not to be in the Avengers. Personally I think it'd also be cool if they put Spider Man in Iron Man 3.
-What happened to Red Skull too? last we saw he was blasted to another dimension. Hydra has to make a comeback at some point.
-Also they need to introduce some more characters either in their own movies or cameos in others. Key Avengers in the comics include Ant-man, Pixie, Black Panther,& Red Falcon.
-Fantastic Four Reboot? with Chris Evans as Capt we need a reboot of the Fan 4. Or a re-introduction of Dr.Doom. Doom is amongst the most dangerous villains in Marvel comics And he's given SHIELD one hell of a time.
-Another personal little complaint of mine is that they don't play up Tony Stark's alcoholism, I understand why (bad message to little kids) but it adds a layer to the Character of Tony Stark not seen otherwise.plus If they do Civil War as a storyline I want this bit of dialogue in the movie
