Restless for the 2.2 patch to go live, players have been flooding the official forums for updates on long requested features: surnames, player housing, engineering revamp, to name a few. The response to all these requests was the same: we'd like to implement these ideas, but don't know when.
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.
