With the simplicity of expanding the storage later, I doubt they want headlines with such prices. The vast majority of gamers won't need more than 825 for at least the first year or two as the big AAA start to come out. And the more we wait until we buy an expansion, the lower it will cost.
I expect a year or two after launch I'll add a 2TB nvme and I'll be set for the rest of the generation with 2.8TB, if games are twice the size of the ps4 games with only a few exceptions that might reach 200GB like there were a few exceptions at 100GB on PS4. And my 1TB is feeling a bit short towards the end.
Also that 2TB nvme is taken out at the end of the generation and used elsewhere, be it ps6 or PC or laptop, or even a PS5 slim, or a PS5 Pro, etc.... Paying $100 more for proprietary storage feels like money thrown out the window.
