Don't worry, I can already predict the changes.
Assassination: "Rupture" has been renamed to "Vile Poison" and does nature damage instead of bleed.
Combat: "Killing Spree" has been renamed to "Blow the Man Down", and "Bandit's guile" has been renamed to "Swashbuckler's Guile".
Subtlety: "Slice and Dice" has been renamed to "Blade Dance", "Fan of Knives" has been renamed to "Shuriken Barrage" and "Honor Among Thieves" has been renamed to "Shinobi's Honor".
And then to go along with that for Artifacts, Assassination will go retrieve previously unknown daggers with poison vials built into them from Putress' grave or the Plaguequarter/Plagueworks in NAxx/ICC. Combat will retrieve the cutlasses of the first Bloodsail captain from the haunted wreckage of his ship at the bottom of Vashj'ir. And Sub will colllect a pair of ancient pair of tanto from Pandaria.
