Brute for SSD will nor help nothing currently SSD NVMe are barely faster than SATA SSD and speed is theorical in games.
They need to step up from a software point of view. I expect SSD to go faster on console than PC.

It's time to review some next-level M.2. NVMe in a sixth gear, yes we review the Corsair MP600. Of course it is an SSD you can seat into any PCIe 3.0 compatible PC, however, if you place it into a ...

This a 5 GB/s SSD. Divide the speed of the SSD by 4maybz it will what you have in game if we see PCIE 5 SSD soon
With faster SSD with a software environnement not made for it I expect SSD PCIE5 or even 6 to not have performance near the max theoretical at all. It will probably worse for CPU bottleneck just for read data. I don't even expect any decompression not all people have a threadripper CPU.
Again 15 or 32 GB/s will not be the performance in game performance at all if nothing change on a software point of view. Far from it, if you're need to divide by three the SSD performance. I think PS5 will have be ok for a long time.
And when people or devs talk about PC holding back PS5 or Xbox Series X, it is on streaming side.
If a game is designed around the consoles SSD speed it needs to stutters on all slower SSD if you want to keep the same level of detail and I suppose to it means you need to do a big effort around the data to make the game work on other system and downgrade the experience like Star citizen have problem on HDD.
I would say on SSD the system and game are as fast as the slowest element, the storage.
If there is nothing done on software side for improve OS and filesystem around SSD I don't think something will change.
I expect the SSD speed to be slow down by a bottleneck(CPU?) somewhere and maybe we will see SSD reaching a bottleneck in term of speed in game on PC
