Soon, as all good things do, the story will come to an end. The magic doesn't have to, though. One day, a small child will find treasures from our past. They will ask "Gran, what's a Blu-Ray?" And after much cobbling together of technologies new and old, they will watch a journey unfold. A young unicorn named Twilight Sparkle will be told by her mentor "Make some friends!" A pink pony will speak way too quickly, a yellow pegasus hardly at all. Rainbow Dash will realize her dream and Applejack will keep them down to earth. Somewhere else, Lyra and BonBon will share a smile as only best friends can, and a little grey pegasus just won't know what went wrong. And once more, the old wonder shared will be new again.
Truthfully, I agree with CRB here. As long as the fandom and show has a special place in your heart, it can never truly die. I really don't think anyone will be forgetting all the amazing memories this fandom has brought anytime soon. Plus we still have this year yet for the fandom to top us off with ponies content.
