But that is not caused by these system being Nintendo products. Nintendo has always had two consoles on the market and during a transition period they had to support two old consoles and two new ones when crunch time came. With the Switch Nintendo only has one console on the market, so there is no need to stop supporting the system prematurely. We can't just look at a few examples and say "Nintendo consoles always X" and "Sony consoles always Y". It's the processes behind these products that determine their lifecycles, not the company name on the box.
