I disagree. I think it did what Nintendo was intending - I just don't think they expect much besides giving it a bit of a boost. The inexcapable reality is that Wii is practically dead. PS2 had a more compelling line up a year after PS3's launch than the Wii has now and Wii U doesn't even have a launch date.
There is nothing software-wise that will sell Wii's at this point. What do we have?
Kirby Wii? 1-2m seller at most and the second Kirby title in a year (not that I'm complaining, it's been too long since Kirby had console games)
Just Dance 3? Which is the 5th Just Dance title now. It'll sell, but not really move hardware.
Zelda: Skyward Sword - Easily the biggest draw but let's face it, 98% of peope who love Zelda already bought a Wii so it's not going to move hardware unless it appeals much broader than the traditional Zelda audience.
Beyond those, there's vertually no games out or coming out for Wii at all. There's no hype. Wii U is already announced. Wii is vertually completely abandoned by third parties (even the Raving Rabbids have jumped ship!) and NoA isn't even releasing the great games NoJ/NoE have available.
The price cut did it's thing. There's just not much you can do to sell a system that's on it's deadbed.
