Trixie's EG box has started floating around out there in the wild (Thanks to @TomDanTheRock for the image), and as is the norm for pony boxes, it has a bunch of little blurbs on the back. A few of these could be hinting at what exactly we can expect in the second Equestria Girls movie. While still unofficially announced, there are quite a few things pointing toward it's existence (including this entire Rainbow Rocks line).
Head on down below the break for the text version of the image above. Some is a bit hard to read.
Main blurb: Everyone at Canterlot High knows the Equestria Girls can rock, but will another band work some musical magic to steal the spotlight?
Trixie blurb: My stage style has to be as magical as my music!
Trixie blurb 2: Ger ready to rock CANTERLOT High -- The Great Trixie Lulamoon will amaze everyone with rockin' style like no other!
Front blurb: A Magician never revealers her fashion tricks!
