Will Tom Clancy's endwar's voice command ...

If you had happened to buy tom Clancy's rainbow six Vegas two, then you probably have watched the teaser bonus disc for his newest project ENDWAR. It is a real time war strategy game in which you can fight as U.S. , European,and Russian forces in this world war three setting. Now, with this game gives you the opportunity of hands off gaming by controlling all your forces with voice commands, you can still control them if with a controller if you want. So my two questions are, Will it be an successful and accurate and create new ways of playing games or not, and will those copycat gaming companies try to sell the same idea?
