When Sony initially held its PS5 deep dive earlier this week, they were unclear on whether the PS5 will support full backwards compatibility for PS4 titles. In the presentation, it sounds like Marl Cerny originally said that almost all of the top 100 PS4 games will be playable on the PS5, which is vague and confusing.

Sony has now updated its article on the PlayStation Blog, voicing their “belief” that “the overwhelming majority of the 4,000+ PS4 titles” will be playable on the PS5.

These games are “expected” to “run at a boosted frequency on PS5 so that they can benefit from higher or more stable frame rates and potentially higher resolutions.”

However, this will also be evaluated on a title-by-title basis. They have already tested hundreds of titles and are preparing to test thousands more closer to launch. Unfortunately, Sony’s statement remains unclear on which PS4 games (or how many) will actually be playable at launch, but they promise more updates in the coming months.

The problem with all this is the fact that they’re using language choices like “We believe”, “We expect” and “potentially”, which doesn’t exactly inspire any confidence in their part. It proves that Sony themselves don’t really know the fullest extent of PS5’s backwards compatibility yet, even though we’re only eight to nine months from its Holiday 2020 launch date.

As of now, it definitely sounds like not all PS4 games will be playable on the PS5 (either at launch or post-launch). In comparison to the Xbox Series X, the PS5 is sorely lacking in that department, as Microsoft’s next-gen console will support all generations of Xbox games, from the original Xbox to the Xbox One.

Here’s their full updated statement:

“A quick update on backward compatibility –

With all of the amazing games in PS4’s catalog, we’ve devoted significant efforts to enable our fans to play their favorites on PS5.

We believe that the overwhelming majority of the 4,000+ PS4 titles will be playable on PS5.

We’re expecting backward compatible titles will run at a boosted frequency on PS5 so that they can benefit from higher or more stable frame rates and potentially higher resolutions.

We’re currently evaluating games on a title-by-title basis to spot any issues that need adjustment from the original software developers.

In his presentation, Mark Cerny provided a snapshot into the Top 100 most-played PS4 titles, demonstrating how well our backward compatibility efforts are going.

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.

Stay tuned!”
