Sony’s recent revelations reveal that the company has had PS4 in mind soon after the PlayStation 3 was released, as it’s made known that PS Vita and PlayStation 4 were being development simultaneously.
Speaking to Edge, Sony’s president of Worldwide Studios, Shuhei Yoshida revealed Sony’s strategy when creating a new platform.
As soon as we launch a platform, we have small number of tech people move on to planning for the next. As soon as the PS3 launched in 2006, I’m sure some parts of the company, especially those hardware people who work in R&D and the semiconductor [area], must have started the R&D effort.
Full development on PS4 only began in 2008, however, when a ”larger, more cross-sectional team” began working on both the PS4 and the PS Vita.
PS Vita was a shorter project compared to PS4, but Mark and Worldwide Studios were involved in both projects, and we worked on both projects simultaneously.
It’s no wonder that cross-platform play will be a seamless thing on the two consoles.
