Even though inclusion of RT hardware etc came as a surprise last gen`s expectations concerning the silicon`s raw capabilities became mostly reality. And that was when we still had a good fab progress cadence.
We´ll get about half a classic node shrink step from RDNA4 to RDNA5/UDNA and another 30+% higher wafer prices at the same time. Closing the 40/60% performance gap to a 4090`s raw power within that one generation would be a leap we haven`t seen since back when Moore`s Law was still in full effect, and then we`d probably still be talking about a ~300+W die with at least a 700+$ price sticker just for the GPU.
Let`s just say I admire your optimism
As I see it there are limits to how expensive you can make a console and still expect it to sell and I don´t see Sony eating huge losses on each console ever again.
My bet would be that we´ll get something around 9700-9700xt raw performance coupled with a zen 5 (maybe even x3d) and a lot of ML upscaling/framegen and whatever else they can come up with. Maybe we´ll get ML features like what we`ve seen from Nvidia`s Blackwell AI suite custom-hardware accelerated. As standard features things like that could maybe make a difference..but that is to be seen.
