OP was not all that well reasoned, especially with what info we had at the time, but it's still an impressively good call from the fall of 2016. Also, kudos to supporters who made actual arguments. I freely admit to having underestimated the Switch, no issue there. As one can note from my posts involving the PS4, I was also skeptical of that, but I want to add that the Covid-19 pandemic was really hard to predict, and it provided a historically unprecedented lift of the entire market (mostly concerning PS4 LT sales from my side). Not just consoles, but phones, PCs and PC components, TVs, streaming services, and even entertainment-related furniture. Additionally, it would seem that both PS5 and Xbox Series X (no one really wants the Series S...) have an artificially high level of demand due to the ongoing component shortage. The market has been absolutely wild since the start of 2020 and I don't think a single soul could have seen all this in 2016.
What surprised me the most in this thread from reading it again was the relatively poor outlooks from quite a few Nintendo fans.
PS: Always be prepared to be wrong, that's why I write so in my posts. And if you are, own up to it, otherwise, you never learn anything.
