Magazines in Japan are printed on very low quality paper, which is why they can get away with selling something with twice the page count for 40-80% of the prize of a regular book. They're meant to be easily used and then disposed of. We don't really have this option since our printing situation is very different than in Japan. Our books match some of the highest quality prints in Japan, so keeping it the same would likely balloon the cost of a single magazine to ~$50.
A lot of changes would need to be made in order to make physical magazines financially viable (for us and our customers), so that's one of the biggest hurdles. I would like to look into the possibility of creating a best of 2017 compilation sometime next year, which I think would be the most likely first step. That said, it's far too early to make any promises, and with all the other projects we have in plan for physical releases in 2018, it might not come to fruition.
