Unfortunately no, considering all the work that's being mass produced, at this rate things are going to get stale within two years and eventutally and cause the fandom to collapse, by then the only peop that are still part of the fandom will be creepy 40 year olds.
Take the Rangerphiles for example, they were like the bronies of the late 80's, but look at them now:
Instead of looking at one way a fandom the fandom will die, perhaps try to look at how the fandom will live on (then eventually die).
For example, the furry fandom is one fandom I'm surprised at how long it's been healthy and how much self-support it has. The fandom runs on nothing by itself and what content the fandom makes itself.
Of course, the Brony fandom is mostly supported by the show. However, this means when the show is over, perhaps we might develop self-support like fan-made episodes.
While the fandom will eventually die off, leaving a few obsessed fans behind trying desperately to give the fandom life-support. But we can't expect that anytime soon. There are MANY loyal fans of the show and we still get more people in the fandom than those who leave every day.
I'd go more in-depth into this subject, if I wasn't on my phone while at school.
