Yes, that tiny ship in the red circle in the Ghost from Star Wars Rebels. When Disney acquired Lucasfilm, the idea was to make all the films and shows connectible in some way. And, what better way to connect the first real battle between the Empire and the Rebel Alliance, than to have a cameo or two from the group who started to cobble the Rebel Alliance together, Star Wars Rebels.
Entertainment Weekly‘s Anthony Breznican did tell his followers to keep both their eyes and ears open for the Star Wars Rebels cameos:
"Actually … one more note: Fans of the Disney XD animated series Star Wars: Rebels should keep their eyes wide open for a number of special surprises. (That’s all I’m going to say about that.)"
So, if we know that the Ghost is in the film, what could we be keeping our ears open for? Perhaps a reference to one of the Star Wars Rebels character names? I guess we will have to wait and see.
