What do I want from the sequel trilogy?
Two words... Darth Caedus.
It doesn't need to go down exactly like it did in the EU books, and we know it won't since they've said they aren't adhering to the EU for the sequel trilogy, but that doesn't mean they can't pick things from it to go with in their own ways, and the concept of the Skywalkers' generational struggle with the force is a must, so what could be more harrowing and iconic than Darth Caedus? A story about the Solo twins and this coming between them would simply be amazing, and more than that, it would work to establish itself as its own entity that filmgoers could enjoy while keeping a glimmer of the EU that so many millions of fans love.
Just a thought.
.....Never let modern day travesties harm the memory of greatness.
I don't think Disney are in the same league as Warner or Google when it comes to being aggressive in the market or abusing their position in it for their own financial gain and customer abuse. Lost count of the number of scandals attached to those two.
