Wow! Twenty days before the official release date, for the states anyway (Dec. 18th). It is interesting, the suggested retail price for the five disc set is $78, while for the 4 disc it is $35. Seems like a lot of money for a tin box and one extra disc. Are they completely different discs? Or is it really just one extra disc and fancy packaging. Regular packaging fits better on the shelf anyway, and one extra disc just doesn't seem worth that much money.
