So, this was a panel at an officially sanctioned Lucasfilm event, filled with it's employees? The odds of that being an open and unbiased affair, are about the same as having a snowball fight on Tatooine. ;)
I'd be willing to bet any Lucasfilm employee who publicly criticized any aspect of SW would be pinkslipped pretty fast.
The interesting question is, why the PR attempt at blowing sunshine up the garbage chute now, five years after the last film?
