Super Nintendo and Super Famicom are the same, just different names for different regions. And as I said, SNES got discontinued a year after releasing N64 in EU, two in case of USA.I didn't say Super Nintendo, I said Super Famicom and it lasted 4 years.
I didn't list the handhelds because I was talking about the patterns of the home consoles, where Nintendo, Xbox and Sony have their own pattern.And I notice that you are conveniently leaving out the handheld side of Nintendo's sales history.
Nintendo's handhelds instead don't have a pattern, so I didn't include them. Some have a very short distance, others instead have a very long. So there's no point of trying to get a pattern from there that they could follow.
