User blog comment:ADour/Official title for Marvel's The Avengers sequel announced!/@comment-4651179-20130721032030/@comment-1895174-20130722020008

If the Spider-Man is new, it doesn't create an expanded universe. Spider-Man is just part of that X-Men franchise. If this new Spider-Man gets his own movie after that, it's a spin-off. No expanded universe has been created.

That it has precedence in comics and television doesn't matter. Comics, television, and film are three different types of media with three different narrative capabilities. Comics and television (particularly animated television) are much closer to each other than either is to film. The only precedence is Iron Man 2, which focused a lot on SHIELD, and is generally considered to be the weakest MCU film for almost precisely that reason. Too little Iron Man, too many Avengers references.

Also, this is not a spin-off. This is the sequel to Man of Steel. I don't know why I have to keep repeating this. And this nowhere near what Marvel and Disney have done. The Avengers is not Iron Man 3. Marvel never claimed The Avengers was Iron Man 3. But, from the get-go, Man of Steel 2 is Superman/Batman.
