Will the 350z spawn more "z" models?

In everyone's estimation, the new 350z will sell quite well due to the niche market it has created. Being that its Nissan's only sports car (The Sentra SE-R is a special model of an existing economy car) will its probable success cause Nissan to make another 200sx, 240sx, 280zx or some other 3 digit number followed by a letter or two? Considering the sport compact market is quite large and growing, it makes sense for Nissan to follow Honda; and now Toyota, Ford and Chevy are trying to a piece.
