yeah this show is going to be too mainstream for them to just throw it at the audiences that haven't watched the animated series without giving background. Otherwise all the more casual star wars watchers are going to be constantly asking "who's this, who's that, why does this matter, why does it seem like we've seen him before?".

Of course, the other route they could take is writing in such a way that you don't really need any of the backstory for this story to be told, but I doubt that's going to be the case for some reason
