If this lawsuit fiasco ever ends, it would be amazing to get Pamela in the ultimate line.
Unfortunately Randy has shot this down multiple times since they don't have her likeness rights. When they made the SDCC retro version the likeness rights were a one time deal before Betsy Palmer passed. I have a feeling once the lawsuit is over and they can resume making new figures, it will be just more Jason's first. Which is fine, Randy made it clear they want to make them all and they will probably be worth the excruciating wait. My hope is that once they've come close to completing the series, they will realize that Part one needs to be represented and a new deal can be made to get her in the ultimate format.
Unless they already had her in the works as a surprise for that unrevealed anniversary set that had to be cancelled. IIRC, it was to have multiple figures and a diorama element of some kind.
