What is known

The blogger’s words could be ignored, butBack in June, he announced the exact release date of The Last of Us Part 2, which was officially announced only in September. PSErebus' tweet also coincides with the words of VICE Games journalist Patrick Keplek, who recently stated (minute 56) during a podcast that the PlayStation 5 is not only the future, but also the past, and Sony plans to take on old franchises.
Given the architectural differences, if the PlayStation5 will be able to run games from PS3, PS2 and PS One, then only programmatically using an emulator. In addition, Sony still has not decided whether their new console will be able to run all games from PS4. So you should take the source's words with a grain of salt.
