Call me crazy, but I think the worst thing Nintendo did was decide to put the next Smash Brothers game on the 3DS as well as the Wii U. Smash Bros is always a system seller, and releasing it on a console every has already leaves people no reason to buy a Wii U to play it.
Also...consoles could play CDs three generations ago, and DVDs two generations ago. Why is Nintendo still ignoring this?
