I don't think HD DVD or Blu-Ray are doing anything great right now. The players are still too expensive, the media is too expensive, and the average consumer doesn't see the value yet. They provide a better experience, but, most people are looking and saying "not worth my hard earned dollars".
Not much can be read into and numbers until the mass market starts buying in.
I bet the winner will be the companies that sell HD DVD / Blu-Ray combo devices.
