Why not? I'll bite.
The X1 and Wii U have opposite problems, but that results in the same end.
The major problem with the Wii U is that Nintendo has done ZERO advertising. If you don't watch Nintendo Direct or visit IGN every other day, you might not know much about the Wii U at all, let alone the games coming up for it.
That's a shame. After the price drop the Wii U is basically asking a fair price for a respectable console, and it's getting torpedoed by utterly inept marketing decisions.
The XBox 1 is the other way around. It has a strong marketing presence, but these days most consumers do a modicum of research before spending $500. Even the least informed gamers know Playstation is in competition with XBox. The consoles look about the same in most regards, but the PS4 is $100 less.
The X1 has a respectable marketing plan, but is ruined by being overpriced compared to the competition.
Now consider that video games are Nintendo's bread and butter. And that Microsoft shareholders want the XBox division gone because it hasn't made money.
The Wii U still can manage second in the generation because Nintendo could, quite easily, advertise the console and fix most of the marketing problems. It's unlikely, but they could do it. Microsoft CANNOT fix the Xbox 1. Even unbundling Kinect, Microsoft has to take a major loss on hardware...which they won't EVER do under shareholder scrutiny.
