It will no way be 4 million. 3 should be possible, if christmas business goes well.
Last year had two of Nintendos biggest titles, though both catching more or less the same Nintendo fans.
This year has a few interesting to possibly very good games, but neither of em is a Mario Kart. As well there is no Zelda in 2015.
Splatoon and Yoshi should do well enough together with the already released games to not fall back to 2013 baselines. But one is new and one is just not that big. I'm 120% sure they wont sell that much consoles.
Devils Third will very likely be pretty niche. I'm not expecting it to do any better than Bayonetta 2, likely worse.
Star Fox might be interesting. We haven't had a new Star Fox for years. But none of the previous ones including the 3DS Remake did to well.
Xenoblade X likely wont be that big in the west. For sure it wont be in Europe. I'd actually bet on that.
Last thing in line is Mario Maker. That might sell well. But after NSMBU and 3D World i just don't see it moving many consoles.
So, if there isn't a really big surprise in the pipeline for 2015 i just dont see Wii U doing any better than last year, very likely slightly worse. At least as long as it is a 290€ console.
And 2016, well, that could be Wii U's last good year. Zelda U, something from Retro and hopefully a few other bigger titles.
