I have heard from Chris that there are several figures completed by him and awaiting Mithril’s production. He has completed the figures up to and including Dunhere (January winner). So he is not that far behind. As for phaeton figures, I have not heard about release dates for sure, other than he intends on producing more.
Remember, he has other contract work which he needs to work on to support his family (Mithril is a small part). I believe he is frustrated a little with Mithril due to the big delays with producing/releasing figures he’s already completed.
