We had a chance to briefly visit the Adult Entertainment Exposition in Las Vegas, and we managed to talk to Digital Playground, one of the publishers of adult movies.
The chap showed us that as well as they supported HD DVD they now only have Blu-ray. He said that Digital Playground will support whatever is out there, and it won't limit itself to one format only.
They have the capability to do this, and some of their titles will be released in Blu-ray. We guess that this won’t help the HD DVD camp.
