By the time they would normally decide to launch a 1.65TB version, there should be plenty of Sony certified gen 4 NVMe drives that are $99 or less.
If you added a 1TB gen 4 NVMe (or newer), you're looking at 1.825TB of storage instead of 1.65TB.
You'd actually be getting more storage overall for the same price, considering the storage upgraded SKU usually sells for $99 more.
It would just be more convenient for consumers who don't want to tinker with the hardware, as simple as it may be.
Odds are SNY will leave room for an internal NVMe no matter what revisions happen to the hardware.
