Going by what I remember from the Secrets of D&D seminar at GenCon, I'm pretty sure monsters will have levels similar to character levels.
For encounter building, I distinctly remember the designers (I think it was Mearls speaking) saying you would choose how much an encounter is supposed to be worth, then pick monsters until they equal that experience value. So, for a 4000xp encounter, you might grab a 1000xp monster, 2 monsters worth 700xp, and 2 worth 800xp.
