The 3DS had it even worse than the Wii U, since the DS line had several versions with very-similar names some of which were variants of existing ones, and a couple of which were actually totally new platforms (was it the DSi that was the other one? I can't even fully remember and I'm way farther down the console-nerd path than the vast majority of people)

At least they just put a number after this one, so folks will get it this time.

That hardcore Switch gamers have been asking for.

Most people I know that own a Switch use it rarely and casually. For them a mere hardware iteration isn't enough of a reason to get the new one. I would suspect that a good 60% of Switch owners fall into that category. However, even if it only gets half of the sales that the switch had, that would make it the most successful current generation console.

But then again, consumers can be surprisingly loyal despite such economic factors. So it may still end up running off like a bandit.
