I really don't get what's so unbelievable for people to imagine that the Switch II would be close, or even better, than a PS4pro.
The Switch 1 was already an "Xbox360 pro", with a more modern architecture even.
Considering that mobile hardware has progrssed comparatively faster, considering that DLSS is not available for other consoles, and considering that there are diminishing returns to improving visuals, having a Switch 2 capable of running the Matrix demo in decent conditions should be the floor for the new Switch. In the end, it will still be about 1/3 of a PS5, but DLSS will help bridging the gap.
Also, Microsoft did Nintendo a solid by making the Series S, but the new Nintendo Switch being a success could also help the Series S in return. Good stuff all around, I'm looking forward to next year.
