So, the mystery items that Blizzard CM's were not allowed to unveil when they announced the honor reset have been released on the PTR's a mere day later, confirming my opinion that there was zero good reason why this information should not have been available at the same time as the rest of the announcement. The honor system gets new cloaks (the last set of PVP cloaks was added in patch 2.3 and requires PVE badges to obtain), upgraded Battlemaster trinkets (also last upgraded in 2.3, though they were available for EITHER honor OR badges), and gems obtained via Honor are no longer soulbound or unique-equipped (a nigh meaningless change, since these purple-quality gems offer fewer stat boosts than green quality Northrend jewelcuts).
Overall, very underwhelming changes, and it wasn't at all worth holding the community in suspense in the hopes that something interesting would emerge amongst the promised "special items". The only interesting news is that the current PTR build slashes the price of the blue-quality 2-minute cooldown Medallion of the Alliance/Horde, from nearly 17K on the live realms to 8K. Since my mage has 5K honor that's going to expire with the expansion anyway, I could obtain the trinket in exchange for grinding out 3K honor sometime between now and Nov 12th. Still, overall, this was a big PR debacle for Blizzard.
