I disagree. Granita was recently trademarked and her name wasn't present in either Rokkon's or Stonedar's bio. Mattel wouldn't spend the money trademarking her name if she wasn't on the schedule.
Sky-High is the only pilot that actually has a vehicle and that makes him the most likely to be sold separately and be successful. I bet he was already made and they are just hanging on to him. He might end up being a sub exclusive or traveling convention figure in 2014.
I really hope Granita makes it to MOTUC one day. Sky High seems cheaper to make and I wouldn't be surprised if he were released before her...
