At this point, I think 160m is in the bag. Nintendo just posted the best first quarter to a FY that they've ever had. They are not eager to replace the Switch.
Something that people forget is that Nintendo is extremely conservative on their business side. They are not going to kill off their most profitable console ever to gamble on the next one. Remember that even when they released the DS, they called it a "third leg", with GBA and their home console being the other 2 legs. They were only going to kill off the GBA when they knew the DS was successful. Nintendo likes a sure thing. They definitely are not eager to kill the Switch off. They aren't eager to release a Switch 2, and even when they do, they are going to milk every last drop of profit off of the Switch. People should go all the way to March 31, 2027 when they do their hardware sales projections, because Switch is going to ship at least 1m annually even that far off.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
