Trackmaster Revolution (TMR) New releases

Those promo images weren't leaked, they were from Japanese material along with promos Green Thomas, Black James, Glynn, and some of the Sodor's Legend of the Lost Treasure returnees that haven't made it on to any other material found. Ryan and Jerome is most likely based on an episode from the Extraordinary Engines DVD, otherwise the pack would've been a weird decision to make. I know that some items in the past have little to do with a tie-in, but when it's characters like these it's safe to jump to a plausible conclusion.
