Keep in mind a lot of people were saying "no no no no no no, too soon, too soon" to a 3DS price cut right up until the hour that Nintendo announced one on this board, lol. And the 3DS was never selling as poorly as the Wii U has been and didn't have the benefit of a brand new Mario platformer from launch day either.
The Wii U situation is much worse.
