Ironically enough, with all of this Jabba discussion, I just had an issue with my home's air conditioning system that may explain why Hasbro went back to the well on Jabba so quickly.
Long story short, my AC broke down about two weeks ago and was out for two days during some pretty hot and humid days with only fans for air circulation. Anyway, even with the AC back running, I checked Jabba out and he was (for lack of a better word) "sweating" on the bottom part of his body. It was as if life was imitating art, as Jabba was literally covered in a layer of slime, which has also covered the top of the dais where he sat.
I was able to clean him and the dais off with warm water, and there was no staining, discoloration, or deterioration noted, but there's no doubt that it was a combination of the rubbery material and the AC failure that led to this happening.
Maybe Hasbro doing a new one was to get a more durable mold out there, but it sucks that it's in a 130 buck exclusive pack that I have no interest in buying. Oh well, if the past is any indication, they'll use the hell out of this ,old and we will be seeing it again soon enough. Until then, if the 2010 Jabba falls apart (or if my AC decides to be a PITA again), my 2004 Ultra Jabba will be a fine sit-in.
