The production value for most superhero films from the release of Iron Man and onward (at least insomuch as Marvel goes) is at its highest point and seems to be steadily climbing. What's more, there is so much lore to draw on that the stories just continue seemingly without end. Therefore, it's unlikely Hollywood will stop. There's even rumor of a sequel to Hancock. I also continue to hold out hope for sequels to Sleight and Chronicle (and please tell us Michael B. Jordan's character magically survived because reasons).
