I don't get it
What are they foreshadowing?
This expansion is aimed at teen girls.
Teens, most teens that I deal with every day, are the exact opposite of friendship. All they care about is love, violence, drugs (mostly alcohol and weed and that sort of stuff), stuffty music (i.e. Nicki Menaj, who wrote a song that goes "Stupid hoe stupid hoe stupid hoe stupid hoe" over and over). They care about fashion and looks and they don't give a stuff who you are as a person. They are unbelievably shallow, and often horribly mean-spirited. This is what I have gathered from those around me. There are exceptions, of course, but those are few in number.
You get the idea. This show is going to attempt to turn the ponies toward a teenage audience and in doing so could easily completely ruin what made the show good.
I love it when channels try to target their teenage audience, but only end up making fools of themselves.
Wait a minute...

Look at Twilight.
No wings.
I almost wonder if they aren't taking the show in two directions at once with the same characters. That would be pretty darn ridiculous. Split continuity presents a LOT of confusion, as evidenced by close brown townysis of the Legend of Zelda series timeline.
