Disney has always been notorious for lobbying the government to increase the number of years that creative works stay out of the public domain. The reason IP and copyright laws have gotten the way they are is probably because of them. I guess we'll never get that crossover when Captain America meets the Fantastic Four and realizes that he and Johnny are the same person (maybe in a weird, Fight Club sort of way).
Speaking of future Avengers, I'm pretty sure that Edgar Wright is still going to make an Ant-Man movie. It's strange that Marvel would pick a stylish and semi-author director like Wright, since they tend to pick more workmanlike directors that can get the job done quickly and cheaply, like Jon Favreau and Joe Johnston. Regardless, with Edgar Wright directing the film the result will probably be spectacular, but not make as much money as Disney would have hoped.
