I feel like that’s a bad example as consoles tend to be household items rather than individual ones. Regular releases mean that people can choose their upgrade schedule and always have a recently released product available. Good example is cars, manufacturers release a new version of each model every year, but the differences are fairly minor. Then every 5-10 years they do a major revision to the model that’s a significant change. This way most people don’t feel put off when they buy a 2-3 year old model and a revision come out the following year, but a person can buy a new model after 5-10 years and feel like they got a significant upgrade from the previous one.
