They seem to have a healthy sense of humor. In the one I saw, Vader is chased around by screaming fangirls after the Rebels show them a picture of Hayden's Anakin.
Speaking of animated Star Wars, the "rights and clearances" credit on TCW and Rebels confuses me. What on earth has to be cleared to use in a Star Wars show? It's not like they use top 40 songs or anything.
