As you can see, Bloodthirsty is the "generic" name given to EVERY SINGLE ONE of the new designs (or revamped), and knowing Blizz, it will be special....suuuuure.
*Edit- Brian stated in comments that these are all available from the vendors using honor points. What is changing is that they will become craftable in 4.2.0 as well as go from a i352 to a i358 and drop the "gladiator" from the title.
Here is an example of the stats, and as you can see, they are currently sitting at i358, which probably won't move much, so we at least can figure something is in stone. As of right now, it seems that the mats are the near to the same as the current craftables....which in other words just means profit, profit, profit for those that make them.
Now some folks are already predicting that the recipies will only be drops from raids/etc in Firelands, but I am not a believer of this. These will be added to the trainers like every other "mass" set of gear that is out there. No reason for blizzard to drop blue recipies for a whole "tier" of gear in instances, so if you are the stockpiling type, and you have a "crafting" profession, getcha mats ready for when 4.2.0 goes live.
