Datamined Scarlet Crusade Cosmetics on the Patch 10.0.7 PTR

wowhead.com:

More datamined cosmetics on the Patch 10.0.7 PTR indicate that players will soon be able to dress up as their favorite fanatical religious sect, the Scarlet Crusade! Keep an eye out for the Scarlet Zealot's shield, cloak, and chest piece on the Trading Post sometime this Spring.

Although we don't have any associated models yet, the Scarlet Crusade should be very well known to players, as they're well represented throughout many of World of Warcraft's vanilla questlines, particularly throughout the areas of old Lordaeron. Some of their iconography is also already obtainable in game, such as the coveted Tabard of the Scarlet Crusade. So the models associated with these items may be unknown, but it's a good bet they'll feature the same colors and icons we're familiar with. There's even an unused Exile's Reach shield model, which may not be related, but certainly looks like it fits the theme!
