I'd rather wait for a potential boxset. And if more people in Japan had that mentality, singles would officially stop being made.
Uh no. There have been experiments to see whether or not straight to box set form would work. Fate/Zero was part of that experiment, and while it sold almost 43,000 copies in week 1, it made less money than if the show were released in singles as it was guaranteed to sell at least 30,000 copies per volume due to the rabid TYPE-MOON fanbase in Japan. Also considering the very high production values, I'm wondering how much of a profit they even made. Probably nothing massive.
Bakuman. 2 is another show being released straight to box set form, but I'm puzzled as to why they would do so with that show. It's not going to sell a ton of copies, and they'll just lose even more money on that project.
Another experiment being done is with Black Rock Shooter. They're releasing the box set and singles at the same time. I wonder how that one will turn out.
Straight to box set form does not work well for the majority of shows, especially those that have very high production values. If Guilty Crown were released in box set form (The entire show.), while it would be like $700, and maybe sell like 10,000 copies total, it would have caused them to lose a lot of money.
