We've gotten confirmation from our sources that patch 3.3 is set to go live tomorrow. We should be seeing the downloader get the rest of the files after the downtime begins (which hasn't been announced yet). There are no new patch notes just yet, however those should be coming shortly.
We have been working hard today on our patch 3.3 information, and will have a lot of great content for you throughout the day tomorrow. You can check out everything you need to know, and then some, in our Guide to Patch 3.3.
Hang tight! Should be a fun day tomorrow!
