Sony Worldwide Studios president Shuhei Yoshida believes that the PlayStation 4 will have a lifespan of over ten years, just like previous PlayStation family home consoles. Speaking with CVG, Yoshida said with PS4 there is room for growth should games start to exceed the 8GB of RAM, and that Sony plans to support the console for at least 10.
"In the middle of PS3 we really hit the limit with what we could do on the system side," he said. "We wanted to add the cross-game voice chat that many people asked us about, but we had no room in the system memory at all to add it."
"So the PS4′s enlarged, very fast memory allows us in the future to improve and add more new features," he continued. "And at the same time we are continuing to invest and add onto the online services so that, three years from now, the PS4 will be much, much better than PS4 this holiday – and that was the case on PS3 and PS Vita."
Yoshida also said that the lower price point for the PS4 is the result of "lessons learned" from the pricing on the PS3.
"Designing PS4 was all about learning lessons from PS3 – ease of development and the cost of the system is a big part of it," he said. "We always wanted to hit $399 and we designed the system and carefully chose out of all the potential inclusions of the core hardware components and we made a system that we could sell for $399."
