4Gamer inquired with Sony Interactive Entertainment Japan and asia on the reason behind the change, and the house of PlayStation clarified that the model number was necessary due to an change in the internal components of the console.
That being said, they also made sure to specify that there will no change in features or specs for the console.
This is in line with Sony’s model numbering standards, with changes 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, don’t worry, your console isn’t becoming obsolete.
