I would like to say, to give a little feedback (though I doubt anyone among Blizzard actual reads this), I am among the many who enjoy seeing updates to old areas in WoW. I believe this is one of the big reasons many people are excited for the revamped Eversong and Silvermoon city coming in Midnight. For me personally, I greatly enjoy seeing updates to the faction cities, like Orgrimmar and Stormwind. It gives a sense of continuity, adds to the feeling of developing stories, the aftermath of events and that time does not stand still.
. . . now if only those buildings in Orgrimmar that have been under construction since Cataclysm could be completed.
