Sorry, most of the focus is on BOTW so I assumed you were basing you prediction on that because it didn't make sense to base the whole prediction on Series S, an actual game console with a power supply. Though I realize now you were just referring to the ability to run UE5 content.
I am not that stupid to be basing predictions on ancient games that were released 2 generations ago. I am more interested about whether Switch 2 is able to run UE5 capable titles and how well it can rn them. If Switch 2 can run UE5 games, then it will be a nice change of pace for Nintendo. UE5 has really nice lighting thanks to Lumen.
As far as the resolutions goes I expect 1080 as the bare minimum, I am not sure if Switch 2 will do 4K. It will 100% NOT do 4K native, but maybe DLSS upscaled. BotW was still running at 900p on the Switch, I believe it's time Nintendo gets into the 4 digit native resolutions.
My point is, there is no reason Nintendo cannot do a UE5 capable machine in the year 2024 after the Series S was released and retailed at $299 in 2020. There is no way Switch 2 will be costing less than $299. But then again Nintendo is going to Nintendo, they are very unpredictable. So who knows.
