Quoted from VALIS666:Disappointed there are only 25 or so cinema shorts out of the 500-ish they made. But that's Disney nowadays, at the parks, too. Moving out the things that made them famous to make more space for the things that sell now. They have the resources a thousand times over to take care of both. Hopefully more will be added in time.
They are taking the “Vault” approach that they do with their Blu-ray’s and DVDs (and previously VHS). Controlled scarcity, to keep you subscribing beyond the first month or so. Pretty good idea between this and the new content. Netflix kind of does this too, because content expires, but in their case they don’t generally own the actual content which disappears.
