Do you need separate conduits for power and communication cables?
Separate conduits would be required for power and communication cables. As BG and others have said, why not go ahead and run the romex for the power and terminate it in an electrical box with a blank cover. The conduit (again, terminate in an electrical box) could then be for whatever communications cables might be needed in the future.
