Coming soon -- possibly in the spring -- Equestria Girls: The Series
This is not fanart. This is from the New York Times. This is official.
Take a deep breath. Then take the 1 off the JPG and go to the actual link. (I didn't paste the real one because it stretches the page too much.)

I also found art showing Trixie in this style. Hasbro apparently decided the Bratz and Monster High lines needed to be horned in on. (Where are the horns...?)
Again: don't panic. This does not replace the main series, it just adds another show and fills a different timeslot. Think of it as alternate continuity and/or a chance to make Lyra scream in agony.
It could be good. But I still don't think Starshine's bookies are taking any bets.
Don't panic -- but do worry.
