The draft DSM V is now out and available on that link. Doesn't take effect until 2013 so they'll still be doing some listening and revising as they go, but they are indeed intending to drop Asperger syndrome as a separate category. They can't spot the difference between it and what they're currently calling higher functioning autism.
They say, "A single spectrum disorder is a better reflection of the state of knowledge about pathology and clinical presentation; previously, the criteria were equivalent to trying to ?cleave meatloaf at the joints?. "
A strange expression, but I think I know what they mean.
