According to the guru AN-Fun Site’s Blog, there are going to be 3 versions of 「艶華-Enka-（仮）」and one separate release 、「中森明菜 演歌セレクション（仮）」
These are the versions:
艶華 －Enka －（仮）[CD+DVD]＜初回盤A＞@ ￥5,000
艶華 －Enka －（仮）＜初回盤B＞ CD only @ ￥3,800
艶華 －Enka －（仮）＜通常盤＞ CD only @ ￥3,000
Lastly, there is the 中森明菜・演歌セレクション（仮） , which I believe is a collection of Akina’s favourite "演歌" since the artiste name is not Akina but "Various Artists".
So, Akina has realised that multiple versions = more sales, especially if you have an A and B version. I wonder what is the difference between A and B, and what is going to be contained in the DVD besides the recording scenes? The price tag for A version is significantly higher than the B version, so I am wondering if it contains more songs – poll winners + enka that Akina wants to sing?
