Some rather interesting news about the Playstation 3 from GDC on ZDNet. Looks like Sony is doing some research into distributed computing for the next Playstation. This means a task would be divided among several machines through networking. Sony's chief technical officer Shin'ichi Okamoto claims Moore's Law (where semiconducter speed doubles every 18 months) is too slow for them. Thanks 0Wingfan.

Okamoto said the method also appears to hold the most promise for dramatically boosting the performance of the next PlayStation. Game developers have said they would like the next console to have a thousand times the processing power of the PlayStation 2. There's no way to do that with hardware advances alone, he said.
"Moore's Law is too slow for us," Okamoto said, referring to the long-held truism that semiconductor power doubles roughly every 18 months. "We can't wait 20 years" to achieve a 1,000-fold increase in PlayStation performance, he said.
Okamoto said Sony is working with IBM to apply Big Blue's research in "grid computing," a variation of distributed computing, to the next PlayStation. While he didn't share details, the plan presumably would involve networked game machines sharing software, processing power and data.
