Why do you think the Wii U will fail, when the 3DS came out of a similar horrible slump and even the Vita has stuck in the fight?

I still think Wii U will start doing better by the end of the year, but the two systems are hard to compare. Nintendo handhelds have been selling well with no exception, from the original Gameboy to the DS. Way better than the respective home consoles too. It seems that there is simply a constant demand for Nintendo handhelds, and every 5 years people are willing to buy a new one.
