Excellent news indeed, and both will be promptly added to my SW library for sure. I love the original Chronicles - probably still the best coffee table SW book. So it'll be nice to add the corresponding Prequel edition, despite my general lack of enthusiasm for those flicks (so far).
And who doesn't love SW posters?! A nice collection of all the posters over the year in one place is going to be very cool as well.
Of course, the price tags are gonna be pretty painful. What was the first one again? Like $150, I want to say, but often on sale from $100 - $125, IIRC.
Regardless of the price tag, I can't wait for these!
