The real question is how can you have conflict when the galaxy is at peace, i don’t think you can do the Sith/Empire storyline a third time. Nor can you do superweapons again.

They fell into the same problems with the EU. Their solution was to create a new enemy the Vong.
Then they inevitably fell into rinse repeat civil war, Jedi/Sith conflict again.
