I agree, and we all know the policy about tie-in material (like Countdown), but people are going to keep calling it the "Hobus" supernova until it's contradicted by on-screen evidence. Thus "retcon"."Retcon"? The movie actually shows it being the Romulan home star, doing a continuous run from Romulus through a rubble field to the star which then blows up, sweeps away the rubble field and shatters Romulus. It always was that, and never Hobus (because as everybody knows, the Romulan home star is called Eisn instead).
