Visual Booklet (I'm assuming this is like a photoshoot booklet?)
On one hand, I'm happy about this: it means reduced production and storage/shipping costs, less physical media that overwhelms the Book-offs and the recyclers and the good wotas who flood the auctions/concerts with freebie discs and goods.
Then: but what about those handshake and cheki photo things? Are handshakes going to cost each DVD-single? That's basically a 100% price increase... Singles are 1,080 and those +DVDs are 1,728 yen. And does this mean cheki events are just not going to be a thing any more? How are they going to change their cheki special box set pricing? Are they (gasp) lowering the overall fanbase price for those events?
I'm hoping that someone's done their market research to confirm that Oricon and Billboard aren't causative factors of popularity... 'cos losing that singles ranking will lose them a tagline in news reports and general public-facing media. And really now, 30 bucks for just 30 minutes of material? Why would I get that, if I just spring some more money and get a whole damn concert? Even DVD magazines offer better value than the singles.
