According to a report from Famitsu, it seems that Sony is still working on ensuring 100% backwards compatibility with the PS4. When asked about backwards compatibility, Sony was quoted as saying (translated by DualShockers’ Iyane Agossah), “Our development team is currently hard at work in order to make 100% backward compatibility with PS4 possible. Please wait for further information.”
The idea of backwards compatibility was initially revealed earlier this year in an article by WIRED, where Sony’s Mark Cerny confirmed that the PS5 would be backwards compatible with the PS4. However, this feature was not mentioned in Sony’s recent announcement, leading some to wonder if the feature could be launched in time or if it could come at a later date through a software update.
