I don’t know if I agree Nintendo customers will get upset that the console may “outdated” in a couple of years.
The Switch was outdated on day one. It struggled to render Kakariko Village in BotW at a steady frame rate. But did that really stop the system from selling millions? Not really. The average consumer kind of doesn’t care about that stuff.
That said, the Switch 2 is certainly more expensive than the Switch 1 so things may be different this time.
