Forsaken guards appear to be receiving a gear update, as we've discovered models for a new cape, polearm, and pauldron on the Patch 10.2 PTR, matching up with previously discovered inventory icons suggesting players may be able to obtain them as well!
Interestingly, the cape still appears to feature the banshee mask iconography which the Forsaken otherwise appear to be moving away from.
We first datamined icons for these pieces in Patch 10.1.7, alongside the Forsaken Heritage Armor and a small update to the shields carried by Royal Dreadguards.
In Patch 10.2, we've also recently datamined new cosmetics for Darnassus Sentinels and Silvermoon City Guardians, alongside player versions, suggesting that there will be some related in-game story content to go along with the NPC updates.
While we haven't uncovered any items associated with these new Forsaken models to indicate they'll be available to players, the addition of inventory icons suggest they may be.
