Filoni doesn't stick to canon lines. Just think, if he is willing to bring someone back from the dead, without explanation, and have them the center of an episode; do you think he cares if he changes the name of some lowly little Corellian freighter? I know, I know, it is a big deal to us, the hardcore fans. But to his viewers, it means nothing. I am telling you, his viewers do not know that the Falcon had another name. And they do not care. The funny thing is, most of the viewers do not know what the Falcon is, or its importance. It is like basenji said, the Prequel Trilogy is pushed for the younger generation, and that is the majority of the viewers of the series every week. I cannot stress enough, we are in the minority here.
