I mean...I guess? We still don't actually know what "Classic" servers are. The point he was making about "You don't want that" was in reference to the buggy, outdated version that we originally played. And we REALLY don't want that(some of you ultra-purist masochists do, I guess?) But a vanilla server with bug fixes and maybe some smoothing out of the more ridiculous gameplay aspects? Who knows, really?
But yeah...talking to your customers only once a year from atop a stage where you preach at them about how awesome your plans are isn't really a conversation. The people who are willing to pay and travel to Blizzcon are already pre-disposed to liking WHATEVER you show them. It's not the same as interacting with your normal community the rest of the year when they have time to sit in the comfort of their own homes and really think about things.
