I doubt MHG will have any considerable effect. I wouldn't be surprised if PS3 manages to beat the Wii the week MHG gets released.
To put it shortly, Wii will remain with bad sales, head to head with the PS3 until WSR arrives, even then, sales could dip really fast, since we don't know how big the WSR boost/effect will be. If Nintendo plans on promoting M+ with only a casual game, then it will probably fail terribly there. It's really stupid to launch an accessory with only one part of the audience in mind. As you can see what's keeping the Wii at abysmal levels is the lack of core content. Having 2 big games to sell M+ would be a better idea, one for the casual audience and one for the core audience, but I'm not fooling anyone here, I doubt we will see another WM+ game from Nintendo until 2010 at the earliest.
