I think it's just going to be on a case by case basis.I think lot of people is playing the low expectations here but I think this time if X PS5/XBSeries game doesn't come to Switch NG is a matter of politics between third party publisher and Nintendo.
It doesn't have to do with anything relate to HW.
I could see a game that's really cpu heavy for example having technical issues on Drake. But of course politics also plays a huge role. Even if Nintendo released a 4090 console, they wouldn't have had third party support on par with Xbox and PS imo.
