The newer films can never replace the Thrawn trilogy. Those will always be the true episodes 7, 8, and 9, the way I see it.
Maybe the movies will be good, maybe they won't. I lean towards the second possibility . . . but regardless of their potential quality, just the fact that they exist pisses me off.
Nothing that Jar Jar Abrams and his cohorts do will ever be worth a damn, because these movies are not sequels to the real original trilogy. They are sequels to the special editions and the prequels, and since I've already negated the existence of those, the new movies are relagated to the same apocryphal status.
The real story of what happened after the original trilogy was already told by Timothy Zahn over 20 years ago. The fact that most of the rest of the EU sucks dog balls does not in any way diminish that. This is my final word on the matter and opinions to the contrary leave me entirely unmoved.
