From several comments I’ve read about what George intended if he made a sequel trilogy, was it really Disney who pushed the EU to Legends, or was that from George? It happened after the purchase, but so did the real development of the sequel trilogy. The way I’m reading the events is that this was an internal Lucasfilm dictate because the films trump the books and related materials.
The 2008 Clone Wars set a major precedent when it basically disregarded the entire continuity of the 2002-2005 clone wars multimedia project.
So yeah, I think it’s fair to say that even if George had been more directly involved with Episode VII he still wouldn’t have felt beholden to the existing EU in any way.
