WoW.com has multiple independent sources confirming the release of Patch 3.2 tomorrow (Tuesday August 4th in the US) and we're happy to pass that information along to you.
There are no patch notes available yet; however, they will no doubt be made available within the next few hours. But really, the patch notes are not going to deviate a terrible amount from the PTR patch notes, so this evening is a good time to familiarize yourself with everything.
The patch will also bring with it some rather significant extended maintenance as well.
WoW.com has compiled everything we've written into a very large and complete patch guide, WoW.com's Guide To Patch 3.2.
Enjoy the patch, folks!
