It's just the angle of the photo that gives an impression of the rear being large. A current 991.2 would also look large from that angle. Once the official photo's start to appear and the overall proportions are more immediately apparent I'm sure most of us will like it. As with everything things look much better in photo's once you have seen the real item in person. That rear light treatment works well on the Panamera IMHO so I'd expect it to look equally as good on the 992. As Aldo has stated that bumper is the Sport Design version so for anyone who does not like the large area of body coloured plastic the regular version may solve that issue.
