The first 10.2.5 PTR has added several dozen items associated with the Trading Post. Many of these are themed around Love is in the Air, but we also have a peafowl mount, more Ahn'Qiraj gowns, and the Quel'Serrar Skyborn Blades. Let's take a closer look!
Two of the items have a cost of 999 Trader's Tender, which likely means they are upcoming monthly rewards: Reins of the Majestic Azure Peafowl and Ensemble: Love Witch's Attire.
There are two datamined Trading Post mounts, one appears to be themed around Love is in the Air while the other is a monthly reward.
The three armor pieces appear to be themed around an airship masquerade--which datamining hints is an upcoming holiday. The Sky-Captain's Formal Attire appearance has been encrypted and hidden for a long time and there's a related set explicitly mentioning a masquerade: Sky-Captain's Masquerade Attire.
