Sony Computer Entertainment boss Ken Kutaragi has confirmed that the PlayStation 3 will feature backwards compatibility with the PS2 and PSone, ensuring continued support for older software formats in the new hardware.
Speaking to Japanese newspaper Asahi Shimbun, Kutaragi-san attributed some of the success of the PS2 to the console's ability to play PSone games as well as PS2 native titles, stating that this was "a matter of security... [PS2] offers a sense of insurance because it is compatible with PSone and DVD-Movies."
This trend - started by Sony with the PS2, as backwards compatibility in home consoles was certainly not the norm before then - is set to continue with the PS3, which will offer emulation for the PS2 and hence for the PSone.
"PSone runs on the PlayStation 2 through emulation rather than actual hardware. PlayStation 3 will offer the same compatibility for PS2 software and the format will continue forever," he explained.
