Sony PS4 Will Use Existing PS3 Cell Processor The impending PS4, which we last heard was coming in 2010 , might be based on the same Cell processor that currently powers the PS3. Japanese tech site PC Watch said that Sony will forgo designing a completely new processor in a cost-saving attempt, and try to squeeze out some moderate technical advancement on its existing investment. Bad news for those hoping Sony would continue its one-upmanship war with Microsoft, but perhaps it means the company's decided to focus on innovation, like the Wii. A new way of gaming with a tweaked-up version of PS3 graphics doesn't sound too shabby to me. [PC Watch via Gamecyte ]
