I hope it is, but that's not at all what I read in his response. It seemed to me that was the Blizz team more or less saying they want to show those events someday & don't want to change the world until those events are shown...in essence, kicking the can down the road. While 11.0 may well be a revamp (which I still suspect it is), that seemed more like a "we just don't want to do it right now" sort of thing.
To his point, he's not wrong. Given the amount of people complaining about world/plot changes happening in books instead of in game, I can totally see why the team wouldn't want to just have Gilneas go back without a questline or the like.
