What Will Never Be on Blu-ray?

Sorry if this is a repeat post. I didn't see anything in searches. Maybe I didn't look for the correct phrasing.

I don't wanna be a pessimist but what are some films that folks think will not be released on Blu-Ray at any point? Or at least in a certain form i.e. the Star Wars theatrical cut, alternate cuts of The Good Bad and The Ugly etc. It doesn't need to be based solely on the edits.

I've been told for example that there won't be an HD version of The Beatles Anthology because it was shot natively in standard def. But I was sure that it was shot in 35mm. At least the later interviews that consisted of the foundation of the documentary.
