Haven't read it past the first line because its talking about the third party event, where third parties put their games has little to do with Microsoft and will be cross gen on PS5 too.
In regards to 1st party we'll have to wait til July to see whether Microsoft is making impressive use of the hardware or just rendering Xbox One games at 4k/&60fps.
I think first few years, you'll see "just rendering xbox one games at 4k/60".
