Sideshow Collectibles mentions on their site that there are less than 30 Exclusive Edition Jessica Rabbit Premium Format figures available, but the good news is that the Regular Edition will feature the light-up base as well.
*UPDATE* The Sideshow website now lists the release of the statue for May 2012, and less than 10 statues remain for the Exclusive Edition. The Regular Edition is still available. New photos of the statue with the light-up base feature have been added. There is much speculation on the material of the dress being changed, as the dress seems to be "baggy" around Jessica's waist in some people's opinion. While there is definitely a difference, there is no word on if this is the final look of the statue for its May release.
