Nah. There was a drywall shortage from domestic suppliers because of the building boom and hurricanes tearing up stuff. Most of the bldgs. w/ problem drywall were built 2005-2006.
I'll bet a lot of homes in the New Orleans area now have this Chinese drywall in them. Lots of residences only had a few inches of water, but it was enough to wick up into the walls a foot or more. Usually, the bottom four feet were removed at the tape joint.
