Kutaragi went on to explain that one of the reasons why the Cell chip for the PS3 was announced to run at 3.2GHz at E3 was due to heat issues. Back when the chip was first announced at the International Solid-State Circuits Conference (ISSCC), its spec said that the chip could run at 4GHz. "We could create a 4GHz Cell if we were aiming to sell it for a high-end computer," Kutaragi said. "There's also the issue of heat. We might have had to create the PS3 with a bigger body if we adopted a 4GHz chip for it."

Kutaragi commented that the PS3's detachable hard drive would most likely be 80GB, since that's the standard capacity of a general 2.5-inch hard drive. "We're going to run an all-purpose OS on it," Kutaragi said, which seems to back up his previous comments that he plans to preinstall Linux on the PS3's HDD.

Kutaragi was asked if he has any plans to add a DVD recorder or home server capability to the PS3. "In that case, you'll need at least one terabyte of disc space" he said. "Even that much space won't be enough if it's going to be HDTV-compliant. To put that much HDD space into this machine is impossible. Rather than to equip some mediocre amount of HDD space, it's better to make it detachable. There's also the possibility of a home server equipped with the Cell chip. But when we first release it as a game machine, we won't need an HDD."

Kutaragi also talked about his decision to adopt Blu-ray for the PlayStation 3 rather than wait a bit longer to see if the Blu-ray and HD-DVD factions would come to a final conclusion on a unified disc standard. "E3 was the last chance," Kutaragi said. "The PS3 is the console of the future, so I wanted an extreme amount of capacity. But for that, we need cutting-edge technology, and not technology that is currently available. My suggestion was to come to an agreement with a physical format that is as close to [the Blu-ray's] 0.1mm as possible. But the PS3 launches in spring 2006. If we had continued to wait for a unified standard, we wouldn't be able to release the PS3. We no longer have any more time. It's game over."

Kutaragi strongly stressed that he has no plans to compromise on the Blu-ray's 0.1mm physical format, which gives it the upper hand to HD-DVD in terms of capacity. However, he said that he could wait until spring 2006 to see if Sony and Toshiba could come up with a unified standard that's still based on the Blu-ray's physical format. As long as the change is only in the disc's logical structure, the PS3 can still adapt to it with some software updates. Despite Kutaragi's comments, it's been reported that Toshiba and Sony are still in negotiations on a standard format.
