I don't see how this is anything but good. All I care about, really, is the new films. If they had to fit with old canon, that would have sucked, plain and simple. No creative freedom there. This is much better.

And new EU stories will not be 110% canon. The thing they're saying about every new thing having the same continuity for the first time is just them making the new EU seem better than the old EU. I imagine them having as much bearing on the new films as the old EU had on the old films.

And anyway, old EU stories will still be in print (they're not rewriting history like someone we know), and new content can and might still take inspiration from them.

Wins all around, I think.
