Have you talked to someone IRL about you feel?
A lot of people thought the fandom would end during the first hiatus, after the first season. Or at other occasions as well...
But we are still there! As long as there are fans, the fandom will survive.
There is still the comics, the fanfics, fan animations, music...
The official comics will have a 'season 10' and continue the story right where season 9 left off.
Maybe we will get another movie even!
And there is also the English version of the Christmas Equestria Girls special that isn't out yet (if you follow the spin off).
And there is still gen 5. It could be really good.
It dosen't have to end.
