The update reads:
During the presentation earlier this week, Mark Cerny suggested Sony prioritized the top 100 PS4 games for PS5 backwards compatibility. The phrasing naturally left many thinking the PS5’s backwards compatibility would be staggered like the Xbox One’s was. However, it seems that’s not the case.
We have already tested hundreds of titles and are preparing to test thousands more as we move toward launch. We will provide updates on backward compatibility, along with much more PS5 news, in the months ahead.
The update also says:
Basically, it sounds like while some PS4 titles won’t run very well on the PS5 without adjustments, that’s not the case with all of them.
We’re currently evaluating games on a title-by-title basis to spot any issues that need adjustment from the original software developers.
Either way, we can hopefully look forward to playing most of our PS4 games once the PS5 launches — and apparently, those rumors of more extensive compatibility were false.
