No, there isn't. Lack of proof is not proof, but I can go to the official Blu-ray Association site and clearly see Apple listed. There was a press release from Apple stating they supported Blu-ray. There have been numerous articles from reputable sources saying that Apple supported Blu-ray. There have only been rumors that Apple would support HD-DVD.
And if you read my post, I stated that I do believe that Apple will eventually support HD-DVD.
