Nintendo hasn't gotten a home console "right" since the SNES in the early 90s. N64 was essentially a flop (compared to previous nindendo consoles, and compared to its contemporary the PS1). Gamecube was a flop. Wii/U is a flop. Wii is the outlier, but I contend that it -should- have been a flop, due to underwhelming hardware (basically two gamecubes duct taped together. didn't even do HD res) and no real software direction at start, but they caught the break of a lifetime due to being the first out the gate with a motion controller, which apparently people thought was a really neat gimmick at a somewhat reasonable price point. How many of those 100 million Wiis sit unused in somebody's closet or under their tv gathering dust, now that the novelty of wii sports and wii fit have worn off? If it is dragged out, it's for the latest release of one of the 4 or 5 franchises that 30-somethings buy out of nostalgia. How often does that happen, once a year? maybe?
The Wii succeeded despite nindento's ineptitude, not because of their business acumen.
What is amazing is that they've been the #1 portable every generation since the first portable generation... That one still amazes me. My 2ds isn't even as impressive as my original PSP, let alone the Vita... Gotta be a price thing.
