From Hasbro by way of Hunter PR:
The STAR WARS Black Series 3.75-inch Princess Leia (Yavin Ceremony) has been delayed due to a production issue with Princess Leia’s robe. However, we are currently working through this issue and you will be able to find her on shelves later this year. Also, we can confirm that the STAR WARS Black Series Princess Leia (Boushh Disguise) 3.75-inch and 6-inch items will be available later this summer.
In addition, you can find a STAR WARS Saga Legends Princess Leia (Endor) 3.75-inch as well as a STAR WARS Mission Series Princess Leia (A New Hope) 3.75-inch on shelves later this spring.
There you have it. The truth on the subject.
