In regards to the NS being in the middle of its life to gauge how accurate this is the is one key aspect and that is the monopoly on one half of the market, when Nintendo last had this or near enough the times between successors increased compared to other platforms for example the NES/Famicom had seven years until the SNES and GB had nine years until the pro-model in the GBC and twelve until its successor with the GBA. Being a hybrid NS can effectively leverage this monopoly to squeeze out more years in its active life regardless of what the competition is doing as it runs on its own merits, a longer run not only means more time to better develop the concept for the successor while letting tech further advance for it to be executed as well as prepare the first year line up but it also allows their recent commitment to spend like $4 billion on things like expanding development teams, infrastructure and so on to be more in place when the next platform is arriving.
Don't be surprised if we don't have a successor until 2025 even.
