Would Microsoft have crushed Sony if the Xbox 360 had had HD DVD built in?

Perhaps, except HD movie sales were and still are far too low to convert studios to the cause. The majority of the movie studios supported Blu-ray during the format war, so the PS3 would have still had the advantage of having the format destined to win. If the 360 had an HD-DVD player, it could have been a disadvantage.
