From my understanding the first paper was published without authorization. So it was likely they were not ready for it to be published. So 2) still seems possible to me. Like what if the team was it seems like we have a room temperature super conductor we need to do more work to be 100% sure though, and then someone then just goes and publishes your rough draft. It could still just be something interesting, and not fraud. -EDIT- Like if the first paper was not released as is let's say after their testing it turns out to not be room temperature and ambient pressure. They could have easily revised their paper to be about new class of super conducting material ect.... or just not published the paper if it was dud.
