The new Return of the Jedi SH Figuarts Darth Vader will be released in October 2019, and will re-use several parts from the original A New Hope Version. The 2019 version will see an updated mask and chest plate to reflect the changes on screen for the Return of the Jedi appearance.
Vader will also come with a lift off panel at the rear of his helmet to reveal the head and a fully unmasked Anakin Skywalker head. To help re-enact the battle with Luke there is a swap out option to show Vader's wrist where Luke cut off his hand. And of course no Sith Lord is complete without his Saber.
Vader will be released in October 2019 and it seems the aforementioned Return of the Jedi Luke will get a re-release at the same time. Also teased in the promo images for Vader are the Emperor's Royal Guards - who have been seen before at Toy shows but are as yet to make it to a release schedule. We also see shots of the new Vader alongside the A New Hope Stormtroopers announced at the same time.
