Obviously, the UK Blu-Ray did not come out last November. It's had a couple of release dates since then, none of which has been kept. Probably never coming out.
I imagine Warner holds the film elements and they probably are waiting to restore them. But when, until the "now or never" point where they can brag about valiantly having saved the film from the brink of extinction? That's what Fox had to do with All That Jazz.
