Today Blizzard reversed their year-plus philosophy of DKs having three trees of tanking and DPS. Tomorrow: Shamans.
You heard it here first!
Tomorrow Blizzard will announce huge changes to enhancement to turn it into a tanking tree. We'll see the return of their shield block talent (5% block chance and increased block value I believe), the buffing of their armor talent, and spirit wolves will be soul-linked to the shaman, making them a powerful aggro and EH cooldown.
I shall rejoice.
And finally level my shaman that last level.
As per the prediction of Iapetes, retribution will become a tanking tree. To retain the DPS capabilities of paladins, shockadins will be buffed.
Lolsmite will become OWsmite. And shadow will be a half-DPS, half-healing spec, used to fix the mathematical problems caused by trying to tune a 25-man raid down to 10 people.
Arcane will become a healing/buffing spec.
Hunters will have no DPS tree. BM will be a pet-tank tree based on buffing their pet and aggro-multiplied misdirect to their pets. Survival will be an avoidance tank based on DoT damage with a semi-useful pet, similar to unholy. Marks will have barely any damage, but absolutely overpowered kiting abilities, and will be used only in WSG to screw up flag runners.
