News is about a week old now, but I hadn't seen it mentioned here and not everyone follows the O-boards.
The important changes are the new single-target ranged taunt, called Hand of Judgment, and the change to AW. Popping wings no longer causes Forbearance, but triggers a thirty-second cooldown on your bubble. Also, the 50% attack speed reduction when bubbled has been changed to a 50% reduction in all damage. This kind sucks for ret PvP, since it means you can't demolish someone while invulnerable. DS is basically just to buy time for heals now. But it's not all bad: for tankadins, we finally get a single-target taunt, which is trainable and not talented, and Sacred Duty is getting its stamina bonus buffed to compensate for its now-redundant attack speed effect.
This is great news for tanks, since now we can use AW again, and more stamina is always good. Plus, HoJ being trainable means that all three specs get a ranged pull for soloing. Which is great for tagging mobs while you're farming, I guess.
