When will the comic book bubble pop?

You can look up any timeline of soon-to-be or in production Marvel movies that just never seem to end. Marvel are planning to release movies all the way up to 2020. Not only are they continuing with the Avengers movies, but rekindling lesser known IP's like GotG, Shazaam, Dr. Strange, etc.

What I want to know is when will this stop? What has to happen for people to stop seeing these movies, or for studios to stop making them? When will the super hero movie bubble pop just like the Dot-com bubble, or the housing market bubble? I've been thinking that since like 2010 that the end of the tunnel was near, that people would EVENTUALLY get tired of an X-Men movie every 9 months, or another Hulk/Spiderman/Superman/Batman reboot, but god damn I was wrong, it just keeps getting worse and worse. The weird thing is that these movies have almost established there own sulf-sustaining culture. You cant argue that the sheer presence these movies haven't rekindled the public's interest in superheros, I dont remember anytime since 2000 when the public at large enjoyed comic book culture as much as it does now, and I think that it is solely due to the insane success of comic book movies.

When will this stop?
