What would Nintendo do if the Wii U begins to sell well rather late in its life?

I ask this because I doubt the Wii U will be able to sell fine until it no longer is considerably more expensive than a handheld.
That may be too late, my question was rather optimistic.

I bought a Wii U from February 2012 this week. A man who went on vacations to the USA in early 2012 bought a few to resell here (Argentina), because he thought it was going to be a big success like the Wii. He had 2 left this week, including the one I bought.
The update took over 12 hours.
