Hortus announced recently that Season 4 was now available on the latest build of the PTR and MMO-Champion and WoR quickly compiled a list of class gear, honor gear, prices and screenshots. Boubouille makes note of a few things to keep in mind:

Season 4 Vendors are now on PTRs. They are PTR stats and could be changed at anytime before the release on live realms.

• Prices are the same as current season 3 items.
• Personal rating requirements aren’t on the items, but will be here in the live version, scroll down to the blue post by Drysc for the details.

You can follow their respected links above for the full scoop. They appear to be updating the posts frequently. WoR is showing two new Hunter weapons and MMO-Champion is showing two new “haste” weapons for casters. I’m sure more will be added.
