The only glimmer of hope the Community Managers could give was about class reviews. Word is Ret Paladins and Enhancement Shamans are receiving "changes" sooner rather than later and for Priests, the Holy tree and Discipline tree will receive some dev lovin'. For those classes not listed and feeling the need for review, there's always the next expansion. TBC did wonders for the druid Balance and Feral trees.
Now we must wait for the Voice Chat patch to go live and then Blizzard can be more specific about what game changes are coming next and which stay on the back burner.
