The editor-in-chief Hiroyuki Nakano revealed some stuff about the new series to expect in a radio interview today/yesterday it seems.
- For the next (new) serialisation meeting they have 15 to 20 series submissions.
- They do not decide beforehand how many series actually get serialised. If you pass "the hurdles" you get serialised no matter how many other series got an ok as well.
- Some new authors for Jump will be 眞藤雅興 and カワサキ (and release in one of the upcoming serialisation rounds), both newcomers. Though the first, SHINDOU Masaoki did the oneshots
Sky Claw and
Joreishi Rentaro no Yakusoku. Don't know who the second is.
- Shimabukuro's (Toriko)
new series will be about Architecture Battles...
- When he became the editor-in-chief in 2017, he made Shimabukuro, Kishimoto (Naruto) and Kubo (Bleach) promise to each make a new series for him (as in while he's the editor-in-chief).
Nakano also used to be Kubo's editor, so look forward to it and shit.
