The other thing that reeks of awesome is the brand spanking new JC bag. Every expansion seems to bring with it new profession bags, and Blizzard seems to randomly leave certain ones out. This time, we get the Luxurious Silk Gem Bag. Combined with the ability to stack cut gems, we're in business.
These will both be particularly welcome changes once epic gems are launched, eventually doubling the number of different types of items gem sellers keep in their bags. Personally, I'm hoping that this change is in preparation for the imminent launch of epic gems in 4.2; however, I've logged into the PTR and prospected some pyrite each build and as yet have not seen anything new.
