I don't see why WSR would sell many Wiis. Most people assume the Wii does what WM+ adds anyway so all they see is another Wii Sports game. If the first one didn't sell them a Wii why would a 2nd? A few would know the difference and we see those few now buying Wiis.
Monster Hunter 3 is another matter altogether because that brings in a different breed of gamer altogether. Shame it doesn't use WM+ but that'd get really tiring anyway.
