The UK release of Things to Come is actually pretty good and would make the basis of a fine BD.
French BD off the port bow, but I'll bet it's nothing we haven't seen before; I assume you're familiar with all this and Trevor Willsmer's comments at Amazon?
Sadly the BFI no longer have the home video rights; they've tons of material for some fantastic supplements, but the rights are now with Studio Canal. And, yes, I would kill for a decent BD of the full length version of the film.
