I was watching YTV [last week, I think] and they mentioned something about the two-part series finale of Justice League.
Then, I was reading a sci-fi magazine [can't remember which] that had an article about the show being transformed into 'Justice League Unlimited' and implied that there would be the addition of new members [supergirl, Zatana, Etrigan, etc] beyond the core seven.
Anyone have any info on this?
