I'm down with what the OP is saying in a very general way (i.e. the specific details may play out somewhat differently). The main thing I would disagree with is a 2025 date for the Switch's successor. I think it will likely be 2023. When Kimishima says they'll support the Switch for 10 years, that doesn't mean they'll have a later release date for Switch's successor. It means that they want to keep Switch going as a lower end system, so that they can still make money on it. Sony kept shipping PS2's out until 2013. That is more what Kimishima means. They want to keep supporting Switch just like Sony supported PS2. Besides, a company makes a lot higher profit margins on a console's tail end. All of the costs are lower.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
