I don’t think it’s likely that Nintendo will burn it all down at the end of the generation. Given the Switch will have thousands upon thousands of games. There is no reason they can’t carry that all over to successor hardware and maintain the Switch 1 as an economy/low tier model with near full support (with lower end versions of software) for years to come.
This is already the most successful model for software playing hardware, and has been for years. Currently the console market is years behind, but I think it’s about to adapt to this model. The burn it all down and start from scratch model is outdated and was never good to begin with. I recall the fuss about SMS and SMD back in the 80s.
I describe myself as a little dose of toxic masculinity.
