In 2014, Disney's got the choice-cut real estate for May/Memorial Day with The Good Dinosaur; Maleficent for 4th of July weekend; and Tomorrowland for Christmas holiday. There's similar situations in Disney/Pixar's lineups vs. Marvel Studios' lineups in 2013 and 2015. Disney movies are higher in the pecking order than Marvel movies.
I do kind of think that those Disney movies are pushing the Marvel movies out of the prime slots. Disney knows they can probably get away with putting certain Marvel properties in non-traditional blockbuster slots but can't with their original, non-franchise films.
