Nissan have just uploaded more pix on their press website.  You can now see the boost button more clearly, and again on the center console (replaces the suspension setting toggle switch).  Looks like other colors will be available too…

View of the seatless rear and the carbon speaker surround.  Speakers should even be there IMO!!!!

Carbon Recaro seats with embossed GT-R logo

Plastic engine cover now black

By far the coolest color….Brilliant White
