Now that the 9.1.5 PTR is live, so begins the datamining, where players begin to find hidden changes to the game, the first day has seen new information regarding legion cosmetic items featuring many new skins that were seen on many NPC's throughout the expansion.
So far the only items found are mainly weapon models featuring the Nightborne and Suramar theme, although we could possibly expect to see more over the course of the PTR, as it is only the first day.
While it is not determined how these items will be obtained, they are likely to be purchased with time-warped badges, the currency collected by completing Timewalking dungeons.

Wowhead data miners also found a Replica Aegis of Aggrimar, which was an important lore item in the Legion expansion.
This item is separate from the others and is tagged as cosmetic, meaning there is only the appearance and it cannot be equipped.
While this may not mean much, it does indicate that there may be some catch-up gear on the Timewalking vendor.
The Legion Timewalking vendor mount has also been found and will be a purple re-skin of the Legion Hippogryph model.
The mount will be purchasable from the vendor for 5000 Timewarped badges, so start saving badges in the weeks featuring Timewalking dungeons leading into the new patch.
