The upcoming PS4 Pro “Rathalos Edition” coming with Monster Hunter World also features the new model number.
4Gamer inquired with Sony Interactive Entertainment Japan and Asia on the reason behind the change, and the house of PlayStation clarified that the new model number was required due to an update in the internal components of the console.
That being said, they also made sure to specify that there will no change in actual features or specs for the PS4 Pro.
This change is in line with Sony’s model numbering standards, with incremental alterations in the second digit of the number indicating minor hardware updates that have no influence on the console’s performance and looks.
If you bought a CUH-7000 PS4 Pro, you don’t need to worry, as your console is not becoming obsolete.
Normally this kind of change is made during the process of reducing the production costs of a console, with new parts that are cheaper to manufacture being swapped in to improve the margin per unit sale. It’s an entirely expected procedure that is often done several times during the life cycle of a game machine.
