As many have pointed out today, it looks like that article from yesterday had a bit of a buried note that everyone missed. Right next to Pinkie Pie and Twilight Sparkle in the toy line is someone named "Adagio Dazzle". A lot of people are guessing that this is the character on the Rainbow Rocks poster in the background, aka Vinyl Scratch/DJ-Pon3. We don't have a whole lot of information yet though. I'm sure as more is released about the movie, we can start putting these theories together.
Thanks to James and everyone else for sending it.
Note: As many have also pointed out, her canon name everywhere else is still DJ-Pon3. Even the comic con toy. I highly doubt they'd change that in ponyland, and if they did I'd venture to guess that this would be exclusive to Equestria Girls for the sake of another toy to sell.
