FPGAs also consume more power for a given clock rate, and their maximum frequency is less than a dedicated chip. It would be unusual to dedicate an FPGA to implementing a CPU. It might change in the future though? I remember some years ago, the possibility of nanotube based chips were being touted, offering FPGA like programmability and speeds greater than a dedicated chip. I haven't heard of it since.
