I would argue that in some respects they would have //less// of a strategic advantage, but that consumers would see the most benefit from everyone getting along and competing on merit on an open playing field. Even in the latter case AMD would still have /an/ advantage as they would at least still be in the primary game, and would also be restricting Intel to targeting that same hardware interface.
