Sounds a little reminiscent of the original PS3, in that it tried to do a lot more than the average consumer wanted to pay for.
They had a cheaper option, but that still didn't work out too well. Depends on what you get for your money. If there was a proper standard PS5 alongside that extra-all version at launch, you'd think there would be no issue. But I don't think that's the case. R&D costs for all those bells and whistles still have to be recuperated, and if the Pro version starts failing, they may very well be in big trouble even if the standard PS5 sells well.
I think we may very well see a Pro version at launch, but I don't think it'll be nearly as big of a leap as the console you just described.
First of all, they have to make sure that the standard PS5 is strong enough to last the generation, and not fall behind the competition in any significant way, like XBO did.
And if the base PS5 follows PS4's trend in this fashion, then 'doubling everything' would be insanely expensive, at launch.
