Look at the PS4 though. It isn't pandering to casuals left and right and it is selling very well. The Xbox One dropped Kinect like a dumb child and it is seeing a resurgence when Phil stepped in and started working for the gamers.
The Nintendo home console systems have never been huge sellers. There is no question Nintendo knows quality gaming but the Wii, in my honest opinion, was an anomaly. It capitalized on a gimmick (for lack of a better word) which was set to take gaming to the next level (and then forgotten when Wii U moved away from it, Move died up and Kinect failed to excite anyone)
If i had to pull something else out of my ass, I would say that the new hardcore gamers (13 to 20 somethings) did not grow up on the marios and zeldas, or even the pokemons. They are more into action/shooter oriented gaming, which is Nintendo's "meh" area. Despite their great, award winning titles, they are ignoring big segments of the gaming market by keeping most third party titles out of their system and playing it safe with their franchises.
Broken record, I know.
