Jeff,
I think the main reason for introducing the 4.0L GTS is to address market resistance to 4T versions in the USA and similarly to a lesser extent in Europe. I think the reason that we still have manual boxes is mainly due to USA market demand. I don't know the statistics but I would guess paradoxically, that PDK is still the majority choice to date.
There have been only a few PDK N'ring sightings so one might assume PDK gets introduced across all 4.0L drive train models in one go. It has to be same engineering save for any minor chassis work which I guess might be rear roll bar location (PDK box longer than manual) and damper revalving and shift point settings.
