There actually are new temp adorns I believe, off the merchant in Thalumbra. http://www.voxdominatus.com/viewthread.php?threadid=941 has a listing of some of the things found.
Those are old.. from last expac. You can still buy them.. and you can turn current expac PQ currency into OLD expac PQ currency to buy them... but they're not new. There is also nothing to spend the zone tokens on.
Thats a negative, I literally just looked and the temp adorns are there. Infused Cognizance of Sathir, Infused Fortitude of Sathir, and Infused Magnitude of Sathir. While it isn't what I expected either, I was expecting like the rare item merchant in ToT, but they are there. Merchant name is Durbain, straight out from the tinker portal.
That is bizaare that they make you exchange current tokens for old tokens.. in order to buy brand new bits Still, only PQ tokens, nothing for the instance tokens? Edit: I just looked.. that guy has always sold recipes and temp adorns. Are you sure they're new?
