Yes, this is real.
So, um, the reason Season 3 was so short is because we're getting a spinoff series this Spring instead!
In this spinoff, called Equestria Girls (I'll rant about the title in a sec), it's basically going to be about humanized ponies in a high school setting.
Now, as we all know, "Equestria Girls" came from a commercial that aired shortly after Season 1. Now this show is just gonna remind me of that. And seeing as how that was the first instance of "pandering to the bronies", that's not a good thing.
The premise is fairly weak too. Ponies in high school? Really? NO.
Now, having said that, there is one good thing to come out of this: humanized ponies. Now, I know that it's usually Dusty's job to make the Rule 34 jokes, but since he's lacking Internet access at the moment, I'll have to do. I, like most people, am attracted to humans. Dusty can do what he wants with horses and clopping. While I don't enjoy Rule 34 ponies, I don't mind it at all if it's humanized, so maybe we'll see more of that.
But at the cost of this stupid show airing on television? NOT WORTH IT.
Seriously, if not for the fact that we already have a Season 4 confirmation, I would leave the fandom. Think about it. Season 3 is ending with Twilight becoming an alicorn, and then we have a TV Movie. This is the perfect way to end a show. Not a season, but the whole damn show. Equestria Girls will just be a "My Little Pony G4.5" to me. Not the same, so I won't watch it.
Except for the fact that G4 will be continuing at the same time. Which basically means, I'm still a brony.
Now, Equestria Daily has a summary of all of the info we know, but it's exactly what I wrote above, minus my personal opinions of course. They do go into more detail about HOW we know this stuff, so if you want to know about that, go ahead and hit that link.
And yes, I know I'm going to hell for linking to EqD. No need to tell me.
