The rather lovely looking 6" Hera figure in the Star Wars Black Series was pulled from its planned release slot in wave 11 (phase 3) due to some "tweaks" Hasbro wanted to make on the figure.
It has now been confirmed that Hera will be included in The Last Jedi release of figures on Force Friday, 1st September 2017. She will remain number #42
There are reports it is the legs that have been refined by Hasbro. The new images shared don't seem to show any significant difference to the original promotional images.
The original Amazon product page for US customers is still live, although the item is marked as "not available"
Kids and fans alike can imagine the biggest battles and missions in the Star Wars saga with figures from The Black Series! With exquisite features and decoration, this series embodies the quality and realism that Star Wars devotees love. The captain and heart of the Ghost's rebel crew, Hera Syndulla was a gifted pilot and leader. Her leadership and the respect she earned from the Phoenix Squadron prompted her promotion to squadron leader by Commander Sato. This 6-inch-scale Hera Syndulla figure is carefully detailed to look like the captain from Star Wars Rebels. This figure features premium detail and multiple points of articulation, and includes a character-inspired accessory. Star Wars products are produced by Hasbro under license from Lucasfilm Ltd.
