Why not quote #1 vs. #1? http://www.eproductwars.com/dvd/ Someday you may be able to say that Blue Ray movies are outselling HD DVD. But right now you can't.
Since I am the one that originally showed that website, if you click show all on the total sales chart, you will see that HD DVD has slowly declined since the release of blu ray while blu ray has shot up, I think we see where the arrows are pointing as of right now, down for HD DVD, up for Blu ray.
