Once the chips are 45nm the power consumption will be below 90 watts and low enough to allow them to shrink the power supply and simplify the cooling system.
The motherboard will be redesigned with higher integration levels to make it smaller.
The Blu-ray drive takes no more room than a DVD drive in fact it can be made even smaller than a DVD drive since it does not need to spin as fast and so can use smaller motors.
It will eventually be just a little bigger than the slim ps2 - i think it will allways keep the big radial fan - this fan is so quiet and smooth.
Weight will be under 1 Kg the high weight of the current unit is partly due to the heat pipe cooling system it's very effective but is also expensive using special coolant, copper tubing and radiator fins.
Dont expect to see this untill 2010.
PS3 number 1 fan
