The short answer is...
Intel decided to goto 0.09 micron, and the consequence of that decision is increased wattage demand which causes thermal bleed, they are trying to cram alot of transistors into a very small space, and it produces a hell of alot of heat, even though they reduced the voltage they still cant get the heat under controll, the only way around it is to further reduce the voltage, and well they cant do it because they couldnt run the CPU at 3Ghz and beyond if they did, so their decision was to step up production on their dual core CPU, which will debut about a full year ahead of schedule. They can increase processing power, and decrease voltage, which in turn decreases wattage demand and excess heat. They have finally hit the proverbial wall at around 4Ghz with a single core it just bleeds energy like a bastard, so the dual core solution is the obvious next step, slow down the Ghz and increase the number of physical processors on-die to achieve parallel processing directly on CPU, makes sense doesnt it, its a very ellegant solution. when they hit the wall with the dual core solution all they have to do is just add more on-die physical processors, 3, 4, 5, 6 inf, when you put more physical processing units on-die it provides a ton of power, in car terms you get raw horsepower and you dont have to crank it to the moon to get the performance out of it.
Imagine a Dual core CPU with HT enabled, thats wicked sick and its comming sooner then we could possibly imagine...
Oops that was the long answer, o well...
