Yay you managed to pre-order! I got the DVD since I don't have a bluray player. Yeah seems like it's the same this time ne?

I was wondering for darn long about the documentary too, before deciding to purchase or not. It seems like it's different? someone on Arashi_on said that it's 80 minutes long, I think the info is from the fan club mail. The NHK was only 45 mins long, and it goes by a different name.
