Eyonix announced tomorrow will be the release of Patch 1.11:

We will be extending our normally scheduled maintenance tomorrow by approximately two hours beginning at 3:00 AM PDT in order to apply the latest content patch. That’s right, I said it—we’re patching tomorrow. Hurry, read this message before it’s deleted! The truth must be told!

Jeff Kaplan (Tigole) announced the closure of Public Test Realms with Patch 1.11 coming out tomorrow:

“A quick and simple thanks to everyone who helped test patch 1.11 on the Public Test Realms. It’s amazing to see that we all share the same dedication for making this game great. With the nature of the MMORPG and quick-turnaround patching, we can never promise that things will be flawless. But we’ll do our best to fix bugs as quickly as possible and show expediency with any tuning issues that might arise.

Just so you know, our internal testing efforts are ongoing. Our QA raid team has spent many hours on every encounter in Naxxramas. Now, they’re focused on Sapphiron and Kel’Thuzad—the encounters which saw the least amount of testing on the PTR’s (unless you count death touch hacking your way through the dungeon =P). Even after patch 1.11 goes live, our internal team will continue to work on the unbeaten encounters in Naxx to ensure the best possible tuning. It’s always hard to get cutting edge content perfect, but we’ll do our best to be responsive should any problems rise to the surface.

No promises as to when the patch is going live, but if I were you, I’d start working on that Argent Dawn rep by tomorrow—either that or pillage the guild bank while the pillaging is good.

Your presence on the PTR’s was greatly appreciated.”
