Most of your predictions make sense, surprisingly. I was expecting either ridiculously low or ridiculously high. So you're pretty good. However, there are some they don't make much sense.
Mario Kart 8 - 13 Million to 20 Million. Nintendo won't miss out on bundling this, after seeing how well it can do with a bundle. Mario Kart 7 is also tracking ahead of Mario Kart DS, even though MKDS is seen as a sales juggernaut. (I know MK7 is on a handheld, and MK8 is on Wii U, but MK seems to continually grow over time.)
SSB4 - 6 to 8 Million (Wii U.) With 3DS it'll get over 10 Million, but I don't see Super Smash Bros. 4 getting only 1 Million away from SSBB. That's near impossible.
Pikmin 3 - 1.5 to 3 Million. For the simple reason that this is an oasis in the desert for the Wii U.
But, really, that's not too bad of a prediction list you have there. I only corrected a few.
