Imagine you have passed some responsability to your successor, like Matthew Wood is the successor of Ben Burtt. How much effort would you put in if you were Ben Burtt, invited to come in for a short amount of time and give your opinion? He didn't left the company without a reason, it was enough Star Wars for him, no real challenges at Lucasfilm. It's not his mix anymore, it's Matthew Wood mix.
I dunno, I'm still more concerned about Wood's input, but I'm also concerned about Burtt's, especially after all the sound issues I hated in AOTC, ROTS and Star Trek.
Oh, and not sound-related, but I watched the scene where Vader and Luke cross sabers in front of Palps and I still see a lot of pink in Vader's saber not only before, but during.
