I really don't understand people claiming the world is empty, the game is a year from release. You don't build all the components of the game up front and spend the remainder of the time simply putting those pieces together.
Different aspects of the development start at different times and take different amounts of time to complete. It could very well be that they aren't very far into the development of generic enemies, NPCs and their programming routines so didn't want to to populate a demo with potentially buggy enemies. Or they simply didn't want to give too much away.
