I hope they don't bring in too many new heroes. Too many characters equals lack of character developement for each character, it can also be a cluster f*** and hard for casual fans to follow the story. War Machine: I think he is for sure going to be in the next movie, it would be hard to explain why Tony Stark's best buddy doesn't help out. I'm still wondering what he was doing in the first Avengers movie, I think it should be explained in Iron Man 3 why War Machine didn't show up in NYC during the invasion. Spider-Man: This one makes the most sense as far as making money and bringing in more fans. Spider-Man is the most well known of all the possible new Avengers. Also in the Avengers movie they were suppossed to show the Oscorp building in the NYC skyline with the Stark tower but couldn't edit the CGI at the last minute or something like that. It all just depends on if Sony and Disney can make some sort of deal. Black Panther: I was watching Iron Man 2 the other day and noticed something, in one of the last scenes when Tony Stark is talking to Nick Fury about the Avengers. On one of the maps in the background it shows a map of Africa with a red circle in one of the countries. On another map it shows the USA with red circles over LA, New Mexico, and New York. Ant Man: Rumored cameo in Iron Man 3 Who else do you guys think should or will be in future Avenger movies?
