Fair point, but without going 'secret sauce' we know that Cerny has helped design the GPU with AMD and purely by proximity, that means that the GPU will run more efficiently on PS5 because Cerny helped design it and the GPU. I'm not saying that the PS5 will be more powerful, not at all, i just think it will be more efficient (not trying to buzzword, i just can't think of an alternative) where as MS may have to be more number crunching.
On top of that, i still remember, very vividly, the start of this gen, on this very forum, where Albert Penello was spouting power of the cloud, Directx10 making up for the lack of power and a whole host of other blatant lies from Microsoft. I'm not saying they're doing it again this time around but...it's getting harder and harder to deny that they may be having problems.
We'll see i suppose.
