Oh, Rarity... You drama queen!
So yes, Twilight's gonna be a princess by the end of season 3. Hence all this alicorn drama right now. I have my own worries and speculations about what's gonna happen to the show, but I'll reserve my judgement until after I've seen what happens.
Frankly, I'm suprised at how the fandom is taking this issue. Yes, a lot of people are expressing how this major change upsets them with regards to what's gonna happen to the show from here on. But that's about it - they complain and leave it be. No one's really going out of their way rise up against Hasbro or the Hub. And on the other hand, quite a few are already warming up to the idea of Twilight being a princess herself, and the powers/responsibilities that go with it. And the rest, they just have fun with it!
Stay awesome, Bronies!
