Well I imagine Mario Galaxy 3 is the trump card.
Either way Nintendo have the option of cutting the price and undercutting the inevitable Sony and Microsoft next gen consoles.
I think its difficult to say either, because the Wii is still doing okay. If they took the Wii off the market the Wii U would take a lot of those sales. They are competing with their own console as well, which was very popular. So they are still making money on that front.
I think the Wii U will phase out the Wii slowly; thus the sales will pick up as more and more games start trickling in. It also depends on the PS4 and the 720. If those consoles are weak competitors the Wii U will do well. At the moment, I think we're all on edge waiting to see what Microsoft and Sony are planning.
