I'm quite positive about it. Disney did just fine and didn't interfere/etc when they acquired Marvel - look how good The Avengers was! Lucas having full creative control was the reason why the prequel trilogy ended up being... controversial, and he was also responsible for the "Greedo shot first" thing and other much-debated edits to the original trilogy. He'll still be on board as a consultant so it should retain some of the proper Star Wars flavour, but it might be interesting to see how someone else handles this franchise.
