42 million.

somewhere between 20-60m but it may be higher than that.

Interesting. Why that specific number?

I correct my prediction (too optimistic):

55,459,673 by January 2018

You'd probably hang yourself if it actually sold 55,459,674 by January 2018.

50-60 million seems reasonable.

20-30 million is low balling it by a lot. There are still plenty of Nintendo fans who will snap up the system once the 3D Mario, Zelda, or next SSB are released.

The big reason behind the Wii U's slow start is that it's competing against less expensive consoles with a much, much smaller variety of new games (as is the case for any console that launches first). Sales will perk up once the PS4 and 720 come out (assuming neither one has a major attractive feature like the Wii's motion control). By then, it'll be a cheaper console (if Nintendo has any sense) with a larger amount of games than the PS4 or 720.

If Nintendo can weather the storm for the next eight or so months, I think they'll be fine.

That's true, 55.5 million by January 2018 is only like 10.5 million yearly.

I voted for 40-50 millions.. Nintendo's first party games aren't released yet, "except for mario 2D"...
But on the other hand, the Wii U doesn't have anything else appealing for the moment..
The market structure isn't the same as before.

60-70 million cause I still have faith

i think it will sell more than ps4 and 720
IF they lower the price and bring their briliant first parties and a proper wii u play casual and have a good third party relation
