This may be a dumb question, but why does everyone complain about the Wii U's small install base as a reason no one wants to publish for it when Xbone has a far smaller install base and has tons of multiplats? Yes the Wii U has been out longer, but that means f*ck all to install bases.
Depending on the next npd numbers, the Xbone may as well be getting its last rites because it will be worse off than Nintendo if the price drop didn't boost the sales by a lot. Multiplats will sell worse and worse on the Xbone over time if sales don't pick up. They're unable to compete in terms of graphical power and because the PS4 already has such a large lead, it will continue to pull in more buys because people want to play online multiplayer with their friends that are more likely to have the PS4. You know Sony wants to stomp on Xbone's throat if given the opportunity, and any failure from Microsoft will be magnified from here on out.
On a side note, perhaps Ubisoft's games on Wii U would sell better if they weren't assholes about Rayman and actually released games that were completely finished instead of sitting on them for a bout a year so they can make watered down ports to other systems. Lately all Ubisoft has done is showed me that, at the top, they are a company I'd dub too stupid to survive in a competent market and will actually celebrate when they have the inevitable AAA collapse that the market is careening towards. I'm not happy at the thought of a lot of people losing their jobs, but the people worth a shit will continue on to find work elsewhere.
Nintendo needs to just consume entire Japanese studios and promote from within Nintendo's family to lead them. Capcom alone has a wide variety of IPs that would be megaton as Nintendo exclusives. Street Fighter and other 2D fighters, Megaman, Resident Evil, DMC (with Kamiya back thanks to Nintendo's relationship with platinum), and Monster Hunter (secured so it doesn't sneak off). That's before we get into long dormant or smaller titles with cult followings. Nintendo has the resources to secure these companies and employ all their manpower and immediately begin manufacturing their own "third party" games.
