Both the Gamecube and the N64 were given a 5 year cycle and they were seen as moderate successes whilst the original Wii was a huge success and was given 6 years. The way the Wii U is going it will probably match the Gamecube sales at best so we should see a follow up in 2017(5 years after the Wii U launch). Sales have been abysmal for the Wii U, I can't see Nintendo being content with 45,000(outside holiday season and the occasional big title) units a week worldwide for another 3-4 years.
