It's been leaked somewhere (I can't remember where), and there was another article in which someone who apparently knew one of the script-writers gave some info on the plot - it may not be true, of course, but I thought I might as well put it here.

The films will revolve around Jaina and Jacen Solo - they'll both be great Jedi, then Jacen will go dark-side. I've heard no mention of Anakin Solo though.

That's it, in a nutshell.

I honestly doubt those characters even exist anymore (not that I care, I don't give much importance to the EU).

i enjoy the Expanded Universe solely for the extension of the story. In no way shape or form do i want them made into a movie. I just can't see myself getting as into the Solos as i did with the Skywalkers. Don't get me wrong, i will see it anyway, but no matter how good it is, i will always look at the sequels as the red headed step child of the Star Wars family

While I'd love the Sequels to be made to fit with the EU at least vaguely, I'd be incredibly surprised if the people crafting the story having given any of it more than a cursory glance. Nor do I think I'd particularly want an adaptation or reinterpretation of already published EU stories.
