That Collector's Edition sounds amazing, every time I saw the butterfly/hand print design inside the game I had to fight the urge to take a screenshot and post it here. Spiffy looking is an understatement. I went with the standard version, alas. The art book sounds great too, but then I'm a crazy concept art fan boy.
Gazzoid: I enjoyed the story at the start of the game, but it really takes off at the half way point in my opinion.
