That's a redundant statement.
No media fight has ever gotten to Joe Six Pack when it comes to home video or home audio.
SACD vs. DVD-Audio? Nope, J6P isn't interested in a format war.
Betamax vs. VHS? That's about the CLOSEST you can get. I think I knew one person growing up that had a Betamax player, everyone else had VHS.
HD DVD vs. Blu-ray? Nope, J6P isn't interested in a format war.
It will always be like this. The consumers that were willing to buy into either format were choosing Blu-ray on almost every count more often than HD DVD.
And no, the consumers will not get the same audio and video on HD DVD titles making their way to Blu-ray. Watch and see if Transformers doesn't have a 24-bit uncompressed PCM track on it.
