It's possible that it was just a stall tactic by not going full boar with it. It certainly would have changed the game had it been standard in the 360 that's for sure. I don't think the cost impact of adding it would have been as bad as Blu-Ray implementation on the PS3 as the HD-DVD players were noticeably cheaper at their launch, but it probably still would have been a big financial hit at the time the 360 launched (or was in development).
