If they drop the price early in the year, I´m almost 100% sure that it will sell more in 2015 (maybe up to 40% more)
Now, if they keep the same price (or wait until holiday to drop it) then I think it will sell less. Why? well, this year it will be competing with a $350 X1, and (unless you're a hardcore Nintendo fan) I think it will be really hard to convince people to pick up a console where they are going to be missing most of the popular games coming in the next few years, for almost the same price.
Not to mention the fact that, it is almost certain that it will also be competing with an even cheaper PS360. And to be honest, I think most of the sales the Wii U has lost in the last two years, it has lost it to these two guys. I think most of the (now teenagers) boys who got a Wii as a gift from their parents when they were kids, are now getting the PS360 to catch up with all the games they had missed on the 7th gen.
