Here is the description for the Katniss doll:
The 2013 Hunger Games Catching Fire KATNISS Barbie #X8251 will be released in October. Official Mattel images of the exact doll are not available but we are hoping that she will replicate this image. As soon as we have more details we will post them for you! This image is from the Hunger Games Catching Fire Movie Promo material and modified to include the item code numbers of the Mattel dolls to be released this fall.
