It all depends on whether the studio decides to actually handle an ensemble superhero movie correctly. None of them have, yet. We always end up with two or three characters that get all the screen time, with the rest just acting as plot dispensers; and the plot's designed around set pieces instead of, you know, being "organic".
The Avengers was pretty sloppy, but it had its good bits. I credit all the good in it to Joss Whedon, and anything crap to the studio and the material. Let's face it, he didn't have great material to work with. That team and its stories have needed rebooting for a loooong time.
