Sony tried to make an ultimate BC console with the PS3. It was too costly so they kept in the PS1 compatibility to ensure fans had some form of BC. If PS5 had PS1 compatibility, that would be confusing and honestly unnecessary. What is there not to understand btw? PlayStation and Nintendo software legacy is MILES ahead of Xbox. If they were to make let's say a PS1-4 backwards compatible and N64-WiiU backwards compatible console, they would have every right to sell those super consoles for $1000+ easy.
