Is there a usual lifespan for a gaming console? For example how long did the NES, SNES, N64, and GameCube stay in mainstream? Is GameCube still alive? I saw a lot of RIP pics for GameCube all over the internet last holiday season, but yesterday I noticed new titles available for the GameCube at the store. Side question: Does Nintendo usually wait a year before they release the different colored version of their product? Should we expect Holidays 2007 to have new colored Wii's? Also because Wii's are selling so well, can an expected price cut be expected soon?
