Who knows. I expect N64 level sales for Zelda, Mario Kart ( not bundled) and maybe Mario 3D World. As for Smash Bros goes, I expect something slightly the Wii sales. Maybe 9 million.
          This is for the people who may wonder how much I think the Wii U will sell life-time.
                  North America: 21.67 million- Come on. Zelda, Mario, Metroid and so on along with heavy marketing will make the Wii U strong in NA for sure.
                   Europe:16.43 million- Sonic will help the Wii U in Europe because Ninty is publishing it there. Sonic is big in Europe as we all should know by now. Game & Wario is the kind of game European people would play because they enjoy collections of mini games for some reason. I am European so I should know but I just don't get it.
                   Japan:9.78 million: Maybe Dragon Quest 11, Monster Hunter 5, Animal Crossing Wii U and Yoshi/Kirby are gonna raise attention if they get made... eventually. I just don't see Nintendo doing that well in Japan.
                   Rest of the World: 7.16 million
                    OVERALL: 55.04 million

Do you even do any kind of rudimentary research before you type? 9.78 million is not bad for Japan by any stretch of the imagination. It is a very solid number...

zelda and mario cart will help console sales

            Who are you  kidding? Wii U will do well in NA because of Mario, Zelda, Metroid, Smash Bros, etc.. Please, don't try to argue with that. Those series always did well in NA. FACT. For Europe, I am also right. Sonic does great in Europe. FACT. Game & Wario is the WarioWare Smooth Moves of the Wii U and that game did the best in Europe. FACT. As far as Japan is concerned, I named huge series in Japan. DQ games ( except 10) sell millions every time. Monster Hunter is the best selling Wii U game in Japan besides Nintendo Land( Duh) and New Super Mario Bros U (  Double Duh). Animal Crossing and Yoshi/Kirby need no introduction.
             9.78 million is not amazing. It's a tad bit  better than the N64 numbers in Japan and that is not saying much.

most of these sound correct but Nintendo would have to sell at least like 30 million wii u's to get to 10 million sales for a game. Unless a game does something like Wii Sports did which was sell almost as many copies of the game as the consoles.
