The sheer amount of content is hard for anyone to keep up with, and we've been steadily updating the WoW.com Guide to Patch 3.3 with everything we've written about the patch (over 250 articles now). This weekend we went through and did a large updating, sorting through a few things and polishing it up.
We heard last week from a few sources that patch 3.3 will be deployed tomorrow, if Blizzard was able to fix the last few remaining bugs. We haven't heard any updates on that yet, but will let you know as soon as we hear anything.
Check out the guide for all your patch 3.3 goodness, and be sure to keep an eye on WoW.com over the new couple days!
