An Evolving World

On a few sites now, I've seen screenshots from the beta, showing structural damage to buildings from when Deathwing attacked.

I'm just wondering, is this going to be like the bridge in Lakeshire that's been under repair since vanilla, where those buildings will remain smoking and billowing with fiery embers until the next expansion, or are we going to see reconstruction take place?

I like the graphical detail and demonstration of Deathwing's destructive power... I just know I wouldn't live in a burning building. Eventually you have to bring out the fire brigade and get things put back together.
