Sorry but I don't see any mid-gen refresh in the OP.
Can somebody point it to me please?
There isn't one.
It's a base-gen refresh / side-grade with improved wifi and bluetooth, more PCIe lanes in the I/O (probably gone from 2 to 4 lanes PCIe 4.0 to use the WD SN740) and a new gamepad that mimics the DualSense's haptics.
Same price as the 2020 release but took out the bluray drive so you can't share discs with your friends and the retailers get cut off from the reseller margins.
