Strategy: publish in the high-impact established Nature-family journal, but publicly boycott the no-impact new Nature-family journal. Win-win.
edit: added -family suffix to clarify that I completely understand these are two different journals from the same publisher.
edit 2: I now understand why the editor of the new journal was hitting senior people up for personal meetings at ICRA last week. He didn't want to hear about our work: he wanted hints to help him on positioning.
