I'm very excited about this announcement and really curious how the line will go. NECA has some interesting choices to make for character selection, since many of the likely collectors for this line already have the Palisades figures. For example, I would be hesitant to buy a Sam Eagle figure because my Palisades one is fine for me. But, there are other Palisades figures that could use an upgrade, like Rowlf, Piggy, and Kermit, and they would likely be bought by many folks who already have a Palisades collection. Since Palisades canceled the line before making figures of characters like Sal, Nigel, or Louis Kazagger, I expect NECA won't make these figures either. If there wasn't enough interest back then, I doubt there will be now - unless the new special is a huge hit and a new successful series starts.
Here's my just for fun guess on characters that I think we're likely to see in the line based on my guess about interest for Palisades collectors and generally in Tiers of likelihood.
Tier 1: Kermit, Fozzie, Gonzo, Piggy, Rowlf, Animal
Tier 2: Janice, Floyd, Dr. Teeth, Zoot
Tier 3: Bean Bunny, Mahna Mahna and Snowths, Bobo, Lips
Tier 4: Crazy Harry, Wayne and Wanda, Statler and Waldorf
I'm so excited to see what's coming for this and their Sesame Street line!
