Well, Hasbro FINALLY confirmed that S9 will be the last season of the show. Equestria Daily - MLP Stuff!: Season 9 Confirmed To Be Final Season Of Friendship Is Magic
Nice while it lasted. Makes me wish I'd found out about the show closer to its beginning than its middle.
I talked about this before, but I'll say it again: it's better this way. I mean, the show has been running for nine years now. Better to let it end on a high note and make way for Generation 5, than go the Simpsons route and have it keep going long past its prime. After all, what the show has accomplished will live forever in history.
From what they leak told us about Generation 5, it will go in a route similar to "Steven Universe" and "Star VS The Forces of Evil", meaning it will be less of a "little kid's show". So, stuff like "we can't come out and say that Applejack's parents are dead because it's a little kid's show" or "we can't show Lyra and Bon Bon in a relationship together because it's a little kid's show" will be avoided in Generation 5.
