According to the magazine, the PS3 hardware is currently designed to include the PS2 chipset, meaning the Emotion Engine CPU and Graphic Synthesizer combo chip that is found in the slim model PS2. The PS3 is already quite expensive to manufacture, and incorporating yet another chipset certainly can't help the situation. That said, the report goes on to say that Sony plans to remove the PS2 chipset from the PS3 once their engineers complete work on an efficient PS2 emulator. Some other interesting details came from Ultra One as well. Izumi Kawanishi, head of Sony's Software Platform Development Division, told the magazine that the PS3 as announced is "nothing more than just the basic system." Sony may release models with still larger hard disks or upgraded network features, but the CPU clock speed and memory specs will not change, of course, since all PS3s must run the same games. The PS3 also comes equipped with a "large amount of flash memory," which will be used to house the operating system and all future system updates. Furthermore, according to the IGN translation, "it seems that the hard disk is to be used exclusively for multimedia content and will not contain any system features; users will, after all, be able to swap the built in hard drive out with any standard drive they pick up at a computer hardware store."
