We now know that World Trigger will be moving in the magazine. This is a good move, SQ doesn't really have that much else going on right now and World Trigger would definitely be a top seller in the magazine, I'm sure it still has a loyal fanbase. Their only other recent hit is the new Kenshin manga after it returned and there's not that much else besides that.
The newest, most successful manga in the magazine are either from late 2016 (Moriarty, Kemono Jihen, Kenshin) or early 2017 (****** HxEros). The rest of 2017 and 2018 didn't really seem to have that much going on.
I wonder what they're going to do with Demon Tune, since it doesn't seem to be growing.
