What will happen to Cata gems?

Spell power will be lost in cata, but what will happen to my sp gems? will they change or will I have to just get new gems?

Also I love my holy paly, but he's not very strong in pvp, I wonder if holy palys will become a force to be reckoned with in cata, or at least match mages and locks.


Blizzard is going to revamp all of the gear and gems in the game to other stats which correspond to it. Go to they have an entire list of the gear and changes that they are making to it. As well as a list of gems. Good luck hope i helped
