I think Mario Kart will get about a 50% attach rate by the end of 2014, a good question is will it drive Wii U sales? I'll play it safe and say 4.5 million copies by the end of 2014.

Smash will get maybe 25-30% attach rate since it's a fighting game & not as accessible as MK, again, will it be a system seller? I'll say around 2.3 million by year end.

im sorry but no. NSMBWiiU has sold a little more than 3 mil. thats with it being bundled and on the market for little more than a year. It is a far more popular franchise than either Smash or Kart. you think MK will do more than a 2d Mario with only 9 months? Explain. 

Your Smash numbers make sense...if one wants to pretend their is no 3DS version, which i gaurantee will take some sales away from the WIi U.
