Just like for volume 1 , there will be regular and a special edition.
They are now both available for pre-order on amazon.jp for 463jpy and 5400jpy respectively: Regular - Special
About the special edition: the expensive price is due to the fact there is a bluray included inside, Tsubasa Shunraiki; and as a bonus they are also including a "reflector charm" (付録としてリフレクターチャーム付き!), which I honestly don't know what it is ^^; It's not specified in the description, but it is very safe to assume there will be a new illustration for the bluray case, just like for the special ed. of vol01.
