Koller identified three key tech changes in the new slim: the system's Cell processor has decreased from 65 nanometers to 45. A new cooling system is in place. And there's a new power draw. The result is something that Koller said is more cost-efficient for Sony to produce. He would not say whether Sony is making money or losing money selling the new unit. Often, console manufacturers lose money on gaming hardware, with the intent of recouping revenue through software sales.



The Slim has no on-off switch on the back, using only the standby functionality on the front of the unit.
The launch units will not include Sony's 3.0 firmware, though that will be added to later units.



Koller said that Sony is not considering adding backwards compatibility support to the PS3, a feature stripped from the line a while ago but sometimes requested by some fans. "Backwards compatibility is off the table," he said.
