You have no idea what you’re talking about. Nintendo has oodles of cash sitting around from the Wii days to do whatever they want. And you already stated the reason there isn’t a Switch more powerful than the Series X: not because Nintendo doesn’t have access to it, but because Nintendo doesn’t care about that. More power = more time spent optimizing graphics = less time to focus on making the game fun. That’s Nintendo’s business model, and it works.
