Ahead of any official announcements, Amazon has begun listing ‘Walt Disney Animation Studios Shorts Collection‘ on Blu-ray with a release date of August 18, 2015. Unfortunately there is no official description to be found and the only listed detail is that it runs 90 minutes in length. A cursory Google search proved to be ineffective.
We hope to know more about this title soon and its contents and will update as more information becomes available to us.
UPDATE #1: Thanks to a reader tip (see comments), art for the Blu-ray was found on the B&N site. Going by the images on the cover, it may be safe to assume that the collection will contain Tangled Ever After, Lorenzo, Paperman, Feast and Frozen Fever.
