I'm excited to have Spider-man coming but I think it is a little odd they are losing Captain America. Tons of people wear Captain America shirts around the parks and the next Marvel movie coming out is Captain America: Civil War.
I also find it odd that they won't have the current Avengers meet and greet after Nov 11th. I"m sure the Avengers will be busy at the races, Pasta Party, Kids races, etc. But its kinda crappy you won't be able to get a picture with The Avengers and your medal around your neck.
I'm guessing Spider-Man will be on the race courses, along with Cap, Thor, Hawkeye and Black Widow.
I'm still holding out hope for Ant-Man since the theme of the kids races is "Ant-Man".
