I agree about Bushnell but I think there is some merit to it despite that. I love big N but they're definitely having problems connecting with gamers and staying relevant. Having a lot of cash in the bank from the Wii doesn't mean as much as people think and its no guarantee they can remain in the market indefinitely. This is a company that still does not have an online platform, they need to hire new blood and help themselves a bit here. The Wii U is in a bad way, the tablet is underpowered and useless, their core casual appeal in motion control is now ignored by both consumer and Nintendo itself, the naming and marketing is beyond confusing for casual consumers, system selling software still has not arrived, etc.
The 3DS is doing pretty well but not so great that they can afford for the Wii U to keep tanking. I'm not sure they can get away with this but I think the Wii U needs do over. Third parties don't want to touch it and many were already leaning that way after all of the channel stuffing with Wii software. I used to see a scenario where Nintendo could recover with Zelda and Mario games but I think we're getting past that point already, particularly when you have stuff like those $100-150 headless consoles from Sony coming out.
