In 2009, Sony and Toshiba are to begin mass production of the 45nm version of the Cell processor used in the PlayStation 3, reports Gizmodo. The smaller processor uses around 40% less power than the current 65nm chip and generates proportionally less heat. It also costs substantially less to manufacture. It would be lovely to think that Sony will pass these savings on to the consumer, but given the less than stellar sales of the PS3 we may just see a smaller, more slimline incarnation of the console at a similar price point.

I find it amazing that there are actually 8 cores, but one is shut off during the testing of each console. This increases the yield rate for the chips.
Just imagine if it had all 8 cores working!?
