@OP:
Again, judging sales performances during the normal after Xmas rebound is quite silly, and knowing Nintendo doesn't absolutely need to cut prices and retailers don't need to discount Wiis to sell them even during sales, most people wanting one in this period should most probably have bought it before Xmas.
Edit: And sales being hit by the crisis and profits hit by crisis and weak $ is normal fo Nintendo too, but it remained first anyway.
