I'm not worried about any recent figures EVER being afflicted with this. "Swirls" and "metal flakes" are indicators on older toys, but there's no reason to think it's an issue on more recent figures. The "swirls" and "metal flakes" were properties of a specific type of plastic that was prone to disintegration, a plastic that supposedly is not used anymore. I'm willing to give Hasbro the benefit of the doubt until figures start crumbling again.
This is reactionary nonsense that pointlessly gets people riled up about "SWIRLS" and "METAL FLAKE*" in plastic, when those were never the cause, only a harmless symptom. If you cough, you assume that you had some bile that your body wanted to get rid of in a routine cleaning sequence, you don't assume you have pneumonia. You see what I'm saying?
These kinds of threads are great for people who're interested in older toys, but often they do more harm than good because people often overreact to plastic that just LOOKS like GPS but is not.
Essentially, I tire of people panicking over GPS on newer figures just because they've followed the general guideline to identifying it without taking into account any relevant qualifiers, such as:
1. GPS was mostly seen on early transformers and at this point its properties should be extremely well understood by plastic engineers at this time. The chances of it being used to today are extremely low.
2. In the past 10 years, the number of GPS afflicted figures has been extremely low, most either being rereleases of older molds or late releases of molds from earlier lines. In the past five years there have been no substantiated reports of GPS being used on modern molds. There might have been fragile molds that broke easily, but that is not the same as GPS.
3. On modern figures, you have more to worry about from soft plastic like what was used on Animated figures. At least GPS takes a while to disintegrate after being cast. Soft plastic can wear itself down to sludge in only a couple weeks.
4. There are varying grades of GPS. Some GPS is very sturdy and won't disintegrate for a long, long time. For example, I have a Beast Wars Magnaboss Prowl who's been sturdy for a good 12 years or so at this point. It might break, sure, but 12 years is a long time and ANY figure can just as easily break from something else. All GPS does is put a definite cap on the life of a mold unless it's re-released. It doesn't break a figure from the moment it's cast.
5. "Swirls" and "metal flake" do not mean a plastic is GPS. It just means it has "swirls" and "metal flake." For new figures, all we can do is wait and see and for old figures, well, there are lists upon lists upon lists of exactly which figures are confirmed GPS sufferers. If you think a figure has GPS, don't panic, check to see if it's on a GPS list or if people have been complaining about actual BREAKS.
* There are theories that the metal flake is part of the problem, but that hasn't been proven and I personally believe it still comes down to plastic composition. Just because two plastics LOOK alike doesn't mean they are the same.
