I actually think being able to debunk all the EU stuff would be a reason Lucas WOULD want to make the sequel trilogy. I think that depending on the success of the TV show, who knows, Lucas could try to dovetail parts of the show into a third trilogy. Perhaps he could use new bad guys created for the TV show, remants of which are still alive 50 years later, as new foils for Luke, Leia, Han and their kids. It sounds out there now, but if the live action show becomes hugely successful, a "big surprise" to everyone including Lucas himself, it could change things. It's totally possible that the TV show, if done right, could make Star Wars bigger than its been since the premiere of The Phantom Menace. If this were to happen, it could be blended into Episodes VII-IX, combining both worlds. Maybe some day.
