When the price drops and Smash, 3d Mario, etc. are out I will definitely have a Wii U. I know a lot of Nintendo fans that have no interest in the console right now due to not caring about NSMBU at all which is basically the only big thing Nintendo has put out for the console in 8 months.
The 3DS lineup in 2014 will probably be a big step down from 2013 and more like 2012.
Smash Bros
Yoshi
Bravely Default
are what we have so far. They have already played the 2d Mario, 3d mario, mario kart, animal crossing, and pokemon cards by then and I don't expect any of those series to reappear on 3DS. There is still a lot of time though
