The Switch is on its way to be the best selling console of all time, even when it only has 10% to 20% of the high end games.
So see it like that: Even without those games, Nintendo is selling far more consoles than MS and Sony ever dreamed of, while having a healthy profit on each console from day one. This is something that Sony and MS could never do.
And Nintendo kicked Sony out of Japan, the second biggest country for videogames.
And that is all what the market decided. After all, people chose to buy Nintendo products, even without having a lot of the High end games.
Now imagine this: Power gains are becoming less and less important, and the gap between Nintendo and its competitors are becomming smaller and smaller.If Sony and MS is having this much trouble with the advantage they have now in their favor, imagine when they lose that only advantage they have?
Once the Switch 2 launches, power will probably be a non issue(Given that it will be a 10th gen system), even if the PS5 is still more powerful. Then Sony and MS will be in hot waters, more than what they are in now.
