I don't think it will look anything like that artists impression. To sum up the rumours i've heard about the new sports car concept or possible next Z for the Tokyo Motor Show: There will be 2 new cars revealed at the Tokyo Motor Show, one a near production version of a sports car (either a new Z or an 86 competitor) , and a more wild concept car (that has already been revealed to be the BladeGlider) New sports car will be based on the Juke 1.6 turbo platform. New Z may have a smaller capacity engine. Have heard criticism that the Z34 doesn't have the same look as other Nissan cars, and the next Z/sports car will have more styling cues in common with other model Nissans. (Seems to be a trend Japanese cars makers are following at the moment eg: Mazda, Toyota). The new car will take inspiration from an old model. Again, these are just things I've read on the net the last couple of months.
