Nintendo is hurting. The Wii U isn’t selling, it’s lacking mainstream publisher acceptance, and the core Nintendo titles don’t seem to be energizing the company’s base of fans. Product lines are being bifurcated in uncomfortable ways; the latest Smash Bros. is coming to the 3DS line of consoles first, and will then hit the Wii U console later.
The business has turned stagnant, even if the company’s new releases remain highly-polished and fun. Sadly, that just isn't enough when you're fighting more powerful systems with better developer support, better outreach to press and fans and of course the mobile market chipping away at your market share.
