Let me make this plain:
Had PlayStation 4 and Xbox One burst out of the gate and dominated 2014 with a slew of AAA titles and eye-opening productions that introduced a glorious new era of gaming, the Wii U would've been dead in the water. I mean, more dead than it is now.
The point is that PS4 and Xbox One were relatively unimpressive this year and as such, the Wii U doesn't seem to be dead. In fact, some recent sales climbs have hinted at a possible resurgence for Nintendo's console, which I wouldn't rule out. I honestly believe that because the two more powerful machines slipped this year, Wii U has walked through an open door. No, I don't believe it has any chance of actually beating PS4 or Xbox One in the long run; the bottom line is that it just isn't competitive enough on a technical scale. A few years from now, the Wii U will look downright archaic.
At the same time, you have to admit that it offers significantly different gaming experiences when compared to PS4 and Xbox One, which offer very similar experiences. The Wii U remains a family-favorite device and you really can't underestimate the timeless appeal of the classic mascots, and gameplay that never goes out of style, regardless of any technological advancements the industry makes. If Sony and Microsoft had put their best foot forward in 2014, I'm not sure we'd even be talking about the Wii U anymore. But we kinda are, and it's partly because PS4 and Xbox One haven't delivered on half their promises (yet).
