I'm pretty much with DiFabio on this one.
I don't doubt there are members that have had some sort of oily residue on their figures, but I think we need to hear more. I would like more photographic evidence. I think those with oil need to speak up more about whether the oil comes back after wiping it off, how often they wipe it, etc.
Is it possible that we will see pics of hideously melted abdomens like there was with the DX02? Yes, of course it is, but it seems a little presumptuous to assume it will be that bad or as wide-spread.
Although, Hot Toys has a record of taking short-cuts (in addition to other questionable business practices) I would be surprised if they took a step back from where they were at with the DCD batch of the DX02. As has been said, even that batch leaked to some extent, but it was greatly improved. In my case, I had a little darkening of the bi-cep armor and that's it. To go from that, back to a deteriorating melted mess seems very unlikely to me.
