Strange that Nintendo killed the Wii, huh? It just stopped making the console [UPDATE: in Japan, at least]. So sudden! Odder when you consider that the Famicom, released in 1983, was on sale in Japan until 2003.
But the Famicom (NES, in the West) was followed by the Super Nintendo. And the SNES was a smash hit. The Wii, however, is succeeded by the Wii U. The Wii U is not a smash hit.
