No, Nintendo does this kind of thing every so often, where they’ll just make an incremental upgrade to an existing console, rather than build a completely new one, with a new gimmick. The DSi wasn’t a massive step up from the DS Lite, which itself wasn’t that major of a step up from the DS, and the GBA SP wasn’t a huge step up from the GBA.

At most, they just have a minor additional gimmick, but everything else more or less remains the same. Switch 2’s gimmick is allegedly letting you use the joycons like computer mice.
