"real breakthrough would be a relativistic quantum theory that included gravity..." Yeah, sometimes one has to be optimistic. I'm aware of the limitations of using non-relativistic QM but it seemed to me that this experimental connection, if confirmed, would encourage or even force relativistic work to center stage. Essentially, both theoretical and experimental practitioners could now say 'we've now a concrete stating point'. On reflection, I wouldn't expect a full GR explanation to come easy. Still, it's a start.
