Well, I've been going around to the different trainers and NPCs (and checking the things I already had) - found the following changes:
New Icon for Disenchant
Griftah has been removed from the lower City (Peacekeeper Jadaar has evicted him)
I went hunting for him and found him right outside the city - just about right next to the Southeast gate. He has some new items for sale - "Fine Poking Stick" and "Terokkar Lilac" (4.5g and 9g with honored lower city)
"Wrought by nature's hands over hundreds of years!"
"Rare and exquisite... just like all the others."
Enchant Cloak - Subtlety changed from my prior cheap cost to the current: 4 Small Prismatic, 2 Greater Planar, 8 Primal Shadow (I liked the old price.

)
Enchant Cloak - Stealth (3 Small Prismatic, 3 Greater Planar, 2 Fel Lotus)
Enchant Weapon - Greater Agility (+20) (8 Arcane Dust, 4 Greater Planars, 6 Large Prismatic, 2 Primal Air)
The two new Enchanting Abilities trainable from Grand Master Enchanters are called :
Nexus Transformation (1: 1 small Prismatic) 90 silver (honored)
Small Prismatic Shard (1 large: 3 small) 1.35 gold (honored)
The Zeppelin Masters between Undercity/Grom'gol/Orgrimmar now have a new gossip option of "Where is the zeppelin now?" - every time I tried it though it said "I'm not sure where the zeppelin is right now actually..." Well, until it arrived - then they blast a noise and do a yell emote through the area: "Snurk Bucksquick yells: The zeppelin to Grom'gol has just arrived! All aboard for Stranglethorn!" - at that point her dialogue stated that the zeppelin is in Orgrimmar.
