I think it's the videos of levitating samples that people are getting excited about. At this point it's either outright fraud (unlikely), an interesting materials science discovery that isn't superconductivity (most likely IMO), or superconductivity itself (still unlikely, but the balance of evidence is shifting). If it happens to be the latter, it's a huge scientific leap forward.
