The highest frequency of any digital system is determined, at the end, by how fast the transistors can switch on and off. A really cool thing will happen when asynchronous processors will come out. Asynchronous devices don't have clocked speeds, so the only limitation is the speed of the logic gates through which the signal must go. The problem with asynchronous devices is that they're a bitch to design, because you have race conditions to worry about and you don't know if you can accept the input and such ( since there is no clock cycle to tell you that )
