I do half expect a few characters like Thrawn may return though probably not quite in their original capacity. It's looking like the story is going to go that the Empire attempts to carry on without Poppa Palpy and while there's some infighting, the whole New Republic thing is a no-go too, so there's room from some familiar faces to pop back up...
but we'll see...
Really? That's definitely more to my liking... I tried to read the Thrawn trilogy and couldn't get through the first book. I would much prefer that they take the ideas and do something different. No New Republic wins in under 3 yrs or random alien invasions, no bloody Vong. All of those stories make me cringe. Give me a good drawn out war anyday... that's a good RPG setting. New Republic struggling against the Empire, Empire struggling to survive, and lots of independents and nasty places to get smashed in the middle.
Okay, I'll take the Dark Adepts from Byss in that stew also... we need more lightsabers!
But cloning the Emperor and World Devastators... /yawn. Just because you can't create a better villain is no justification for soap-opera revivals of old villains.
I get it, at the time, it was just a bunch of cool stories that were in comics and continued the legacy of star wars. Excellent. But since it's not canon, I sure hope it's not treated like it.
That is kinda the nice thing about he canon wipe, if you spend any time actually thinking about it you can tell what has hope and what is probably gone forever, at least in the form it was if not totally.
Right now we know for certain:
-The new supposedly canon video/mobile game shows the Empire attempting to maintain control by pretending the Emperor is still alive and Endor was just propaganda, and not really succeeding.
-TFA shows "The First Order" with a very very very Imperial look and feel and the "Resistance" with a very very very Rebellion look and feel. (Almost too much in both cases making me a little worried JJ is just duplicating the original trilogy, but that's another thread)
-The canon wipe announcement said the New Republic isn't a thing anymore.
So it's probably not too crazy to assume:
Endor happens
The Empire attempts to maintain control and power
Various uprisings and infighting breaks out as it becomes clear Palpy is toast
The Rebellion is never able to solidify itself as a new government. (with possible infighting on that front too, though other reasons are also possible)
The First Order comes out mostly-totally on top (either by infighting, transition, coup, or any other number of options), the Rebellion comes out about where it was give or take.
So looking at that alone locks in a lot of little odds and ends, killing plenty of older EU story options (largely good riddance) while leaving plenty of room for characters, locations, and materiel to return should it be decided it's worth the trouble.
So the Vong war destroying half the galaxy over a long weekend... yeah, gone, almost without doubt. But a certain blue art critic attempting to consolidate Imperial power, and ultimately failing... I'm not holding my breath, but it's certainly possible...
