Is there any information on it?
Solid info? Not yet, McCallum hints at stuff all the time, like timeframe and characters (suggested Boba Fett but didn't SAY it). The only things they've said outright is that it'll take place somewhere between Eps 3 and 4, it won't focus on main characters, and won't air until at least 2008.
Darth Vader is becoming the Mickey Mouse of Star Wars.
"We named the dog 'Chewbacca'!"
The use of a lightsaber does not make one a Jedi, it is the ability to not use it.
I don't expect to hear any solid info until later this year or at the rumored CIV.
Up, up, and OKAAAAY!!!
