I hope they come out with more info soon. Compaired to the other classes, it seems we're doing pretty good since we're not getting too many changes.
[blizzard]MAGE
Improved Water Elemental – this talent has been removed and replaced with a new talent that grants Replenishment (similar to Shadow priests).
We are also working on a way to give frost mages Ice Lance "Shatter combos" in PvE.
We are also working on more survivability for Fire spec in PvP.
We are also working on making Spirit a more useful and interesting stat for all mages.
