There was another patch to the PTR's today, and it looks like this patch confirms a Tuesday release for 2.1.

One of the major changes: the "World of Warcraft PTR Patch 2.1.0" was changed to read "World of Warcraft Client Patch 2.1.0" and the link directing you to the patch notes on the WoW website was changed to reflect it being a patch release.

You can check out the full patch notes here, but the additions for today are listed below.

General

• Taunts: The taunt system has been adjusted so that Warrior Taunt, Druid Growl, and Paladin Righteous Defense will now grant the player the correct amount of threat even when the creature or its target is crowd controlled.
