I said that it could be possible that instead of investing and researching bc they could just sell remasters and cut loose to ps4. MS *will* have bc but we don't know how much people care about that. I don't say there is any benefit besides from a user point of view to carry your existing games over in an ecosystem.

I see your point. Do you think Sony would have to invest much to get PS4 games working on PS5? Or will using similar architecture for PS5 make PS4 games work on it with minimal fuss.

Usually I would have said no. But: Sony is allowing devs to code to the hardware to a point where it seems to be a problem with exact timings when the system is not exactly behaving like it should. That is why the Pro goes *completely* in PS4 mode - it is behaving *exactly* like it has to. According to Cerny because of compatibility reasons.

This doesn't seem to be the case with Xbox - MS has also a low-level API but still is able to abstract from this level to get games to run on different hardware, like we can see on the 360 emulator and Scorpio is already said to be not only compatible with Xbo games but will also be able to run the games better (how this turns out, we will of course see when the console arrives).

So MS seems to have a software side solution while Sony seemed to "solve" the problem with changing the hardware setup on demand which actually works for the Pro BUT PS5 will not use Jaguar processors, it will be a new CPU architecture with different timings, caches and internal behavior. You can't mimic an old processor with a new processor.

With PC people actually think this happens but it doesn't - the software does the trick for you. I don't say Sony cannot solve that problem also with software in the end but the Pro and the way it behaves is a sign that this isn't easy for Sony to do and they didn't solve it for the Pro.
