I think the 720 will be in the lead. Next Gen, M$ will have stellar graphics, established motion controls, a superior online gaming network and unrelenting support from third party developers. Through in a few titles soccermoms find appealing and a decent asking price (300$ or less) and there you go. They'll be number one in America and Europe, but probably not Asia. Not unless they get Dragon Quest and Monster Hunter as timed exclusives or something.
