LittleBigPlanet won't boost PS3 sales anymore than a couple thousand. I'm sure that PS3 sales will boost coinciding with the holiday season (so will all of the other consoles, coat hangers, sausages, bike helmets, and crossbows), and that LBP will be said to be the cause of it. Wii Music is more likely to provide an actual boost to hardware sales, but it will pale in comparison to the boost the Wii will get simply from the time of the year.
Wii Music will sell more first week and lifetime, and move far more consoles (but quality likely won't be an argument so it's only a concern of those who care more about sales than gaming).
