I would be really suprised if the Wii U did not sell at least somewhere in the ballpark of 10 Million consoles this year, given the fact that they have managed to sell (approx) 2.6 million consoles (in 6 weeks) without clear direction and little advertising and we've yet to see any real AAA first party title (besides Pikmin) announced yet which you can bet your ass this Fall Nintendo will have some substantial system sellers out there (would not be suprised if they sold 7 Million alone between Septemeber through Decemeber of 2013)
I believe that the only possible outcome of Nintendo only selling 7 million consoles this year would be due to a complete crash of the U.S economy which would basically cause a global chain reaction!
