In my opinion this is all at the wrong timing and 12 CDs is kinda crazy, thats 12k for the whole set... The album, Tokyo Dome, Acchan's graduation and the shuffle are all in the middle of this, as well as the usual singles releases from all the groups, and SKE's album too.
The first song was really good, and I hope the next 11 are, but I worry they are just going to disappear into nothingness. I understand that Pachinko is really big business and rakes the money in, and that this Pachinko machine is being advertised way more heavily than anything else AKB48 at the moment.
