Update: Each cube dude will require assembly.
StarWars.com has an article with accompanying photos, including a look at the box design. The question of whether the CubeDudes were being sold as a kit with instructions or as complete models is now answered. The set contains 416 pieces and some swanky box art.
They will be selling 450 per day. The designer, Angus MacLane, will be on hand on Friday 2-3pm and Saturday 12-1pm. Price is $75 for the set.
