Name calling, grow up.
I'll tell you why and I've had this told me. All the games so far are last gen games, some just released later than the next gen consoles. They all work on last gen engines, Valhalla, Watch Dogs, Call Of Duty etc.
I was told that moving from PS4 Pro to PS5 was very easy, the tools have barely changed and you even have the same number of compute units for your load. You get a big clock boost, you get a big increase in Ram at a higher bandwidth and a huge increase on the CPU side. That is why it was so easy for Cyberpunk to just run the PS4 Pro version at 60fps.
For Xbox it's a bit more complicated , not sure about the tools late scenario but the GDK isn't as familiar and has more changes than Sony, you do get the benefits of Ram and CPU increase but there is substantially more work to be done for the wider GPU that isn't just a big clock speed increase. So you need more optimization to get the same results and time has been short with working from home and getting games ready for launch date.
When we get to next gen engines the picture will be different.
PC games are being released using the same GDK.
Also, (though I'm not 100% sure about this), developers are free to use XDK or GDK.
