Shuhei Yoshida spoke with CVG and wants the lifespan of the PlayStation 4 to be as long as the companies other consoles. The 8GB of RAM is not required in todays games, but he says in the future it is good to have the flexibility for game content to expand and to add system features.
"In the middle of PS3 we really hit the limit with what we could do on the system side," said Yoshida. "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," Yoshida 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 talked about the price point of the PlayStation 4. He stated that Sony has learned not to overprice its console like it did with the PlayStation 3. The PS4 is launching at $399, while the PS3 launched at $599.
"Designing PS4 was all about learning lessons from PS3; the system architecture, ease of development, network services... 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," he later added. "So we just did what we aimed to do and we were hoping that people would like it. I was very surprised about the announcement yesterday by some other company … In a good way."
The PlayStation 4 is slated to be released this holiday season.
