Yep, that's what we're talking about, as there is no Blizzcon 2012.
I was thinking about this today, when the next Blizzcon will be, so that three or four months prior someone can turn up the new Blizz copyrighted title, so we can all start guessing about the next xpac. That's fun. Peple saying it is definitely one thing, other people coming back and calling them names and insisting they're wrong... good times.
Then I started thinking, when are they going to release/announce the first MoP patch? I see March as a good time for a patch, so we might not hear anything until January? Not that I'm already bored with content that hasn't been released yet, but, you know...
Oh, and I expect there'll be a D3 xpac there too.
