Can you explain your question a little more clearly? Do you mean what will a CPU be able to do in the future, or how it will work, etc.?
CPUs right now seems to be getting limited on the amount of cores being able to be utilized by programs(except easily parallelized ones), so basically Intel and AMD are beginning to integrate new features into the CPU, like gpu and, already, the memory controller. Integration is the future as of now, but some day we might have processors that use light for processing instead of electrons, which would push the processing power up many fold compared to today's tech.
Can't really tell what the future will bring, we might have some breakthrough in the next few years, or we may never find a better way to make processors work.
