In the latest build of Patch 5.1, several new items were added.

Amongst the most interesting ones is definitely the brand new Vol'jin model. Even though it's untextured, it gives us a clear idea on how the player troll models could potentially look like, once Blizzard decides to update them.

The second great thing is Vol'jin being involved in the whole lore thing of Patch 5.1. He'll have his very own Scenario.

Another untextured model is what seems to be a mount. For the time being, I've not found any mentions of it in neither of the databases, but we know it's called Wind Steed.

Further Darkmoon Tweaks

In 5.1, we're seing new tents opening on Darkmoon Island, new rewards a pet battle master and much more! In this build, some festive hats were added that will become a part of the Darkmoon celebration.

New events at the Darkmoon Faire lead to addition of new rideable wooden toys. Players will be probably able to summon them regardless of their location during the festival.

We've got the rocket

Murloc

Gryphon

Dragon

and last but not least, the wyvern.

Map Changes - Darkmoon Faire Island

The northernmost tent can now be accessed.

Leaked Sound Files

As I brought you the 5.1 lore development thread, some voices of key characters were missing, now Varian and some others have been added. Just listen to this video, it covers them all.
