They are only needing the same hsf because heat sink design isn't making any leaps and bounds. To require more expensive/exotic cooling hardware will meen less units sold. To reduce the temp of the processor meens increased production cost, which meens less profit margin unless they pass that on to the consumer. They won't reduce wattage unless they have to. They are only going to .13 because they have to if they want to continue increasing speed to compete. They don't care how much you have to pay for the power, they care about yields, costs and demand. You say that cooling requirements will steadily drop till all we need is passive cooling. Why should the trend towards increased cooling suddenly reverse now?
