Sorry if this has been posted already, but based on this concept art, it seems very likely that the soccer ball droid will be Ridley's character's sidekick. We'll probably be seeing that little guy in the film, too. Wonder if he'll be a Yoda type character?
I personally think that having a new droid rather than rehashing/shoehorning R2D2 and C3PO like in the prequels is a smart idea.
