I've seen the Stewie Untold Story dvd, great stuff. Haven't got round to buying it yet though. Family Guy rocks, maybe even more than the Simpsons!
IIRC, if you have the dvd of Episode 3 of Star Wars (the most recent one made), either on the commentary or on the extra stuff, Lucas mentions that there will hopefully be a Star Wars animated series coming out in the future. Apparently he was very impressed with the Clone Wars animation (which you should watch if you haven't seen it) and wants to have the same guy do a whole series. The animator/director was the same person who does Samurai Jack.
I've heard a few more rumours about it but nothing really concrete. Apparently it won't feature any of the well known established star wars characters, but will feature a lot of the planets etc that we have seen in the films.
