Hmm ... I'm not sure about EXILE and Koda Kumi (as they both have a large and loyal fanbase, so we'll have to wait and see), but Ayumi Hamasaki will release a special version of her album (she put the songs inside USB). I don't know if Ayumi fans will bought both version (USB and CD), but I'm not 100% sure that the USB version sales will be included in the CD sales number. So, her CD sales might not be as high as it used to be (and the USB version is very high in demand, Avex even increased the amount of the USB production).
And I'm not worried about NINKI ^^, they never got it right when it comes to DBSK ^^. NINKI prediction is based on a survey that they do. They asked a number of people and asked them whether they know about the release date of an album/single and whether they would bought it. It's not because of THSK previous album XD.
Yep, Oricon is counting the USB version.
I'm surprised at its popularity considering how friggin expensive it is. So I guess it won't make any difference to the sales. The majority of her fans aren't crazy enough to buy more than 1 version. It is more likely that THSK fans will buy multi versions of their album since they're a boy band with many teen fangirls.
Yeah, I don't trust NINKI, there are times when they are really accurate and also times when they get it completely wrong.
If it was me, I don't think Kuu will sell that much and Tohoshinki's sales can exceed her's.
The boys' sales are usually very front loaded, even more so than Ayu so they can pull off a daily #1!
But yeah, it will be an interesting week, with THSK against the queens of Jpop (although with fast declining popularity XD)
