As far as the Goldwyn titles are concerned, the Archive is apparently reissuing Guys and Dolls next month, so that seemingly confirms that Warner’s license for the Goldwyn library is still good. Dodsworth apparently got a new restoration so we should hopefully see that getting a release soon...
I would guess that Captain Blood needs a lot of work before it's ready for Blu-ray. I remember seeing it on TCM a while ago and thinking that the transfer looked pretty rough.
