I think this is true for all minor releases no? Robin hood was the same when I bought at release last year.
I don't have a Robin Hood slipcover, but one does exist.
I am afraid I've missed some Disney blurays, especially with their slipcases, does anyone have a list? The OP doesn't seem to have been updated
Why do you feel the OP isn't updated? It's a complete list of the main animated canon (not including sequels, spinoffs, or other random movies); the only update it needs is switching Aladdin's tentative date to its confirmed date, but I wasn't going to bother. One of the reasons why I didn't include sequels/spinoffs was lack of demand, but the other reason was because other than the DTV sequels to movies that are part of the vault cycle, nothing else goes in the vault. You can still get all of Pixar's movies, all of POTC, all of Marvel, all of DisneyNature, all the Pooh spinoffs, etc.
The main canon movies subject to the vault are:
Snow White and the Seven Dwarfs - VAULTED
Pinocchio - VAULTED
Fantasia - VAULTED (released as a double-pack with Fantasia 2000)
Dumbo - Available
Bambi - VAULTED
Cinderella - Available
Alice in Wonderland - Available
Peter Pan - VAULTED
Lady and the Tramp - VAULTED
Sleeping Beauty - Available
One Hundred and One Dalmatians - Available
The Jungle Book - Available
The Little Mermaid - Available
Beauty and the Beast - VAULTED
Aladdin - No Blu-Ray Release, releasing this October
The Lion King - VAULTED
(all of this is noted in the OP)
The sequels and spinoffs that are currently vaulted but that did at one point have a Blu-Ray release:
Bambi II
Return to Never Land
Lady and the Tramp II: Scamp's Adventure
Beauty and the Beast: The Enchanted Christmas
The Lion King II: Simba's Pride
The Lion King 1½
Sequels/spinoffs that are not currently vaulted but might be at some point:
Cinderella II: Dreams Come True + Cinderella III: A Twist in Time
101 Dalmatians II: Patch's London Adventure
The Little Mermaid II: Return to the Sea + The Little Mermaid III: Ariel's Beginnings
