Capturing Coruscant isn't all it's cracked up to be, since the ruling faction on that planet changes every few decades.
The only way Star Wars could do anything set after Return of the Jedi would be to higher new actors, as Harrison , Carrie, and Mark are no longer up to spec. I'm sorry, but it's true. Of course, by doing this, there would be a huge outrage. Who else can play Han, Leia, and Luke? You could go the way of making the movies into animated movies, but that raises a whole other issue.
Before, I would say the next set of movies need to by the Thrawn Trilogy. I still say that, but like I said about the actors...So, I would say forget the Vong War (too depressing anyway, and the ending to it is a cheap sellout). Do something with Jacen, Jaina, Tenel Ka, Lowie, and the new generation of Jedi. Anakin and Tahiri could be in it too. The original cast can make cameo appearances, and their ages would fit in with the cannon. Of course, this would have to be before so many of the characters were "destroyed" by current events in the books, but I'm sure someone can come up with a story set between the Vong War and Young Jedi Knights.
Nice to know someone else knows about this stuff.
