Regardless of Microsofts fail, I wouldn't ever dream of buying a Nintendo console nowadays, as much as they say it's to "compete" with PS4 and Xbox One, it's not really. It appeals way more to the "family" types and kids, sure 'serious' console gamers might get one, but I bet they'll get either a PS4 or an Xbox One before they do, either that or they're just a massive Nintendo fan.
Most of the games I tried on that last Wii thing, I wasn't impressed at all, there are only a few decent serious games and I'd have to play it with a controller as I found motion control to be a massive gimmick. The hardware isn't capable of running anything that is going to look good compared to the Xbox One and PS4 ( I'd be surprised if it even manages to surpass the 360 and PS3's visuals ) and it's probably just going to have 90% of its games designed for kids, families or fanboys.
Not saying it's a bad console, just saying I don't feel Nintendo is even in the same market as Microsoft and Sony anymore.
