For a complete nerd reference look at new graphics cards. The new Navidia card has a few things that the new ATI card doesn't and yet the ATI card still out performes the Nividia card in frame rate tests.
Anyway what i'm saying is that no matter which new HD format has better specs it still may not be as good as the one with worse specs. It's all in how they are used.
I don't want to get in the middle of this but that is my two cents. I really don't care which version gets picked up. I just don't want a format war like what is going on with DVD-Audio and SACD
