Given the sale numbers that this manga gets (50K volumes on the week when volume 5 was released), I would've guessed that it would go on longer. Whatever, it's been a fun run. I might pick up other Owada Hideki manga.
Anyways, I had predicted this and started ordering Kindai Mahjong issues from fujisan a month ago. I should be able to scan the last 2 or 3 chapters in January. Since fujisan doesn't allow anyone to cancel their subscription for the first 3 months, I'll end up with three extra issues, but whatever, they're $15 each. This isn't a totally veiled request to get donations, by the way.
I currently have no plans to translate the anthology (it's a bunch of non-sequitur 4-komas; you won't be missing much), but I'll scan it when I get it in January as well. The last volume should come out in May/June.
