So taking Dr. Bosch out of the conference in order to get this to the finish line, would almost certainly mean they need him working on finishing up the Journal preparation (Aka: back and forth editing), imo.
if thats the case then that also could very well mean there is still a back and forth with the journal aka peer review stadium and that could mean we are still many weeks away from the publication it also means they have or had more hurdles to overcome the anticipated.
I hope I'm wrong. I have heard different but NWBO isn't good with timelines and gets surprised by NWBO as well.
