DPReview has a very nice interview Hasselblad's manager of technology Ove Bengtsson. Highly recommended.
In that interview he mentions that the planned adapter for HC-lenses does not have AF. Although AF may be added later. This may not be a great surprise, but no great news for X1D users shooting action.
Other than that the discussion is very interesting. He aldo discussing the Lunar stuff, nice to hear soe info from the inside.
He also discusses the GFX briefly and says that the X1D and the GFX are different, with the X1D being smaller and the GFX having more features.
Body construction and passive cooling is also mentioned.
