Well, look at this. After all, the "mysterious masked pony" we saw a while ago really seems to become a major character. This snippet is from a box of her toy. The full picture is below the break.
It says Sunset Shimmer was a student of Celestia years ago. And it kind of announces a "special celebration". That's the reason for the masked ponies we saw on the ToyFair pictures.
I'd consider this to be more than a rumor... So, have a discussion. What do you think will happen?
