This whole idea that Nintendo only supports their systems for 4-5 years then moves on overnight seems to be based solely on their unsuccessful consoles and the Wii, totally ignoring NES, SNES, Gameboy, DS, and 3DS.
DS got Pokemon B&W2 eight years after it launched.
SNES got Kirby's Dreamland 3 seven years after launch.
Gameboy got Pokemon Gold & Silver ten years after launch.
3DS got Ultra Sun & Moon six years after launch.
