Wow, as a long time Star Wars fanatic, I am a whirlwind of emotions right now. I am certainly happy that I will get to see more Star Wars movies. Although I am a fan of the EU, I really hope that the movies continue on from ROTJ, and don't become "spin-off" movies. If that were to happen, along with the supposed schedule of a new movie every couple of years, I would be worried that it would somewhat cheapen the franchise.
Regarding the EU, I have never read any of the NJO stuff, but I love anything from Zahn. As far as the people criticizing Zahn's books, no other SW I know of captures the pace of the movies, and the attitude of the characters (especially Luke, Leia, and Han) as well as he.
I would LOVE to see the Thrawn Trilogy turned into Episodes VII-IX, but I find that very unlikely. Correct me if I'm wrong, but with each book being 400+ pages, wouldn't they need to trim some of the content to turn it into a film anyway? However, that's not the biggest challenge that TTT would face in becoming movies. With Lucas still being the "creative consultant" for these films, and with his disdain for the EU - stating that he believes that Han and Leia never got married - I really can't see him utilizing any of the material from the EU. Which for me, is certainly disappointing.
However, no matter what happens, even if it's "Star Wars: Episode VII; Return of Jar Jar (maybe Gungans live a long time), I'll be in line. And so will you.
BTW, I have now seen a few people apparently agree that the Thrawn Trilogy is "hogwash", but only Jaq has given any specific reasons. Care to elaborate?
