Most, if not all, of the ‘Star Wars: Vintage’ collection is now available in HD on Disney+ (or SD upscales labelled up as being HD?)

• Ewoks: Caravan of Courage
• Ewoks: The Battle for Endor
• The Story of the Faithful Wookiee (animated short from the 1978 Holiday Special)
• Clone Wars (2003 animated series)
• Star Wars: Ewoks
• Star Wars: Droids (coming later this year)

Yet still no HD or 4K release for the unaltered theatrical version of the Original Trilogy available to buy.
