Wii U doesn't need a price cut, not yet anyway.
What it needs are desirable games; Pikmin 3 is a good start, and with Wind Waker HD, Donkey Kong Country, Mario Kart, Smash Bros, etc on the way, sales will improve.
If a console doesn't have a strong library, it won't sell no matter how cheap it is. Cutting the price would do little to spur sales and only make Nintendo bleed money on each unit sold.
