If you want to drop some cash on a new Quilt look into a new material called Dry Down in sleeping bags and quilts. It's new on the market and will be available Fall 2012.
It's regular down with a "nano-level water repellent polymer" applied to the down it's self. It retains 60% more loft, absorbs 30% less moister, and dries 60% faster than untreated down.
Would love to see who pulls the trigger first on this one.
