Faster and faster was never part of Moore's law. It was all about transistor density. Faster and faster stopped in part because of heat problems. Feature size will continue to get smaller for a while, but the schedule will be subject to economic conditions. A new state of the art fab costs in the billions and the price goes up as the feature size goes down. At some point feature size reduction will seriously slow down because of physical constraints. Intel and others switched from bigger CPUs to more cores because the were hitting the wall in design complexity of the pipelines. More cores is a more efficient use of the real estate. There are still tricks to be tried like 3D chip designs.
