Kutaragi hints at PS4 plan

Ken Kutaragi, the 'Father of PlayStation', has revealed that he already has a vision for PlayStation 4, 5 and even 6 - despite having announced his imminent retirement, GamesIndustry.biz reports.

Speaking to the EE Times Kutaragi said that previously he had been unable to talk about "the next step" as PS3 had not launched globally.

"We've introduced PS3 in Europe, so now I can openly talk about" future plans, he continued.

"As a matter of course, I have the vision of PlayStation 4, 5 and 6, which will merge into the network."

According to the EE Times report, Kutaragi has already supplied Sony's designers with ideas for cutting the cost of manufacturing PS3 - and with design models for two years into the future.

He is now focused on exploiting the opportunities offered by connectivity, stating, "The design concept of the Cell processor is the network processor."

Kutaragi announced his retirement as CEO of Sony Computer Entertainment last week. He told EE Times he will continue to have a relationship with Sony but that he will work independently of the company for the most part, adding, "Now I'm ready to start working with a much wider world."
