Live view is all good and well, but that is not going to help wedding photographers and people with similar shooting techniques. I think this new back will shine the light even brighter on the imperfections of the DF+. Amazing resolution is always second to getting the shot in the first place.
I think I'd still choose the Leica S over this new back if I were a wedding photographer and wanted to go MF, just for ease of use.
I think it'll shine in fashion style photography. The ISO will give it a lot of flexibility and the slight crop factor will help with the long lenses.
For landscape shooters it will probably still be the 260/80 unless you don't shoot wider angles.
