I just skimmed this the other day.
From the article-"Why, one celebrates by buying one of these studios’ BD-only titles on HD DVD! Yes, Blu-ray-Only Titles are available on HD DVD. Yes, that is correct."

It appears to me that the whole exclusive format bs is just that-bs. You can get anything you want on either format- you just have to dig a little. Of course renting may be another story.
