Compatibility is a "prerequisite," with cross-generations with PS4 in mind
The PS5 has a "compatibility feature" that allows it to run PS4 games. In the old days, the PS2 had PS1 compatibility, and with the PS3, only the early models had PS2 compatibility on hardware. Later, until PS4, compatibility with the past was shifted to a focus on "cloud compatibility," partly due to the change in CPU architecture to x86 systems.
The PS5, like the PS4, runs on an AMD processor. This would have made it easier to maintain compatibility. In fact, quite a bit of PS4 software runs directly on the PS5. What did we know about the development of compatibility?
Ito: To be honest, I wasn't aware that we had done anything special to make the PS5 compatible. Of course, the processor generation has changed, so we had to fine-tune this aspect, but PS5 was developed with compatibility in mind from the beginning, and it was a major premise that we wouldn't change from x86.
Nishino: In terms of compatibility, it's important to run PS4 titles on PS5, but we also insisted on forward compatibility (supplying PS4 with the same titles as PS5).
Our current assumption is that the transition from PS4 to PS5 is expected to take about three years. In the meantime, how do we make sure that people will continue to buy games on PS4? Will the games we buy be playable on PS5? That's the key.
At a certain point in time, we asked developers to develop games based on the assumption that they would be able to cross-generate between PS4 and PS5. Of course, we also need to improve the library to make that easier.
I'm a little concerned about this in terms of "compatibility.
The PS4 had "mini-apps" that worked within a different framework than games, such as video streaming apps, and the PS5 also has a collection of these apps in a tab called "Media". Currently, we can't show you screenshots because we haven't gotten permission to release them yet, but we're planning on being able to use multiple video streaming services.
