Remastered in high definition is irrelevant for source material that old, regardless of how it was remastered. Do you think the Laurel & Hardy set that came out would look so much better just being slapped on larger discs?
Up-scaled DVDs for the shorts will look nearly as good as the same shorts put on a Blu-ray disc. Unless you have some absolutely ridiculous setup the difference to the eye is going to be negligible. It doesn't make sense for Sony to put them out on that format.
I don't want to start an argument or derail the thread, but that is not correct. Blu-rays, encoded from the HD sources, will look much better than the DVD. I'm a 20+ year veteran in the film industry. I work for a major post-production studio and we author films and other entertainment product on both Blu-ray and DVD. The Laurel and Hardy films would look better on Blu-ray, "IF" the authoring facility used HD sources. Placing SD sources on a Blu-ray disc doesn't really do too much, but if there was an HD source of L&H, then yes, it would be better.
The age of the film is not the issue. There are many old classics making their way to Blu-ray now including Chaplin's "Modern Times (1936)", Buster Keaton's collection with films from 1920-1923, "All About Eve", "Psycho", "Casablanca", "The Wizard of Oz", and many others. The difference is much more than "negligible", however it may not be as important to you, and that is OK. But source material shot on film, as the Stooge shorts were, and carefully remastered and transferred to HD, will look spectacular on this new format.
Back to the thread, I do hope that if there is any new bonus material, that Sony does the right thing and also makes it available separately. A lot of Stooge fans have faithfully bought the entire 8 volume collection, the "themed" single DVDs and the feature films with DeRita.
Looking forward to learning what, if any, of the possible bonus material may be.
