They said a little while ago they are pretty much moving strictly to parting out figures that can be parted out instead of offering them for order boxed (due to their order limits getting slashed). And no more POPOs either since things are difficult to predict before hand. So the Mechanic is likely a figure that will get parted out and the Centurion is likely boxed only. They've never parted out an Iron man armor figure since they don't have much to part out usually (ie no clothes to separate from the body and very few 'accessories' that aren't part of the body as well).
But TA, please correct me if I'm wrong.
