Within console generations, change has indeed always tended to be gradual, but I think the point here is that we're talking about the step up to the next console generation, for which the visual difference in graphical power used to be very large, you could do a lot more on the newer console than the older one, but has become more gradual over time. Many already didn't see the need to upgrade to the new Playstation or Xbox from the PS4 or Xbox One, and a lot of their libraries were backported to the older consoles (granted, the consoles dropped during Covid so scarcity played a part in that but even after production picked back up they're not doing as well overall). The only console that could still likely make a big visual leap to a new generation any time soon is the Switch to the Switch 2, and we still don't have confirmation on whether Nintendo is even planning on such an upgrade. Just like the Wii, it sold like crazy while still being the least powerful in the generation because it had a knockout combination of utility and quality games. On the other hand, it is showing its age now, so if Nintendo doesn't make that upgrade who knows if the fans will continue to support it.
