12k mile update: 4 rotations so far, all tires wearing fairly evenly @ 7/32s. Hydroplane resistance is beginning to diminish @ this point, although overall wet traction is still very good and dry traction is outstanding. They still seem about as smooth & quiet as day 1. They'll be taken off the car for the Winter season in about 1 month. I anticipate being able to (at least) drive through the Spring of 2013 @ the current rate of wear. Thats not too bad, considering that they're on a daily driven, heavy, AWD car. I'll definately buy them again, unless Conti Extreme DWs significantly drop in price.
