Well, at last some info from Hot Toys customer services. I got an email from them this morning saying that they will replace the body of the DX02. This is all I can ask from a manufacturer who has made a mistake. But a word of warning to all you guys waiting for the mythical 3rd batch. Bad news I'm afraid, this was part of my mail reply
"the oil leakage problem has been greatly improved in the body that we are sending to you.
There may be slim chances of leakage, but it shall not cause much inconvenience to your enjoyment of the collectible figure"
They have been very polite and friendly in their responses to me, so I guess it really is a problem they do not know how to deal with.
Regardless all I wanted was an offer of a solution, and their email today has restored my faith in them. Now whether I actually take them up on it is another matter, probably cost me as much to post the damn thing back to them as get a new one!
