The PlayStation Blog has announced they believe that “the overwhelming majority of the 4,000+ PS4 titles will be playable” on the upcoming PlayStation 5.

This news comes via an update to the accompanying blog post to PlayStation’s The Road to PS5 presentation.

Mark Cerny (Lead System Architect of the PlayStation 5) stated during the presentation that they had tested the top 100 most-played PlayStation 4 titles for compatibility. Now, PlayStation have confirmed they have already tested “hundreds” of titles, and are preparing to test “thousands more.”

PlayStation state their high-hopes to bring “the overwhelming majority” of the PlayStation 4’s library to PlayStation 5.

“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!”

The Road to PS5 presentation also revealed the PlayStation 5 would use an SSD, ray-tracing, 3D audio. Cerny boasted that the system could practically eliminate load times (when a game was installed on the SSD), thereby revolutionizing games not needing to be designed around loading game assets.
