A : I think it will depend on how the show ends. If the show has a good ending then I think the fandom will continue to expand the same way Trekkies and the brown coats did, but if the show takes a wrong turn and ends on a bad note then It probably wouldn't grow as much. But either way all decent sized fandoms have continued to expand after their shows ended and I don't see any reason why the brony fandom would be any different.
