Nissan 370Z-based mule spied

Is there light at the end of the tunnel for Nissan Z fans waiting for a 370Z replacement? A test mule based on the 370Z has been snapped at the Nurburgring, suggesting Nissan has started work on a replacement for the long-serving 370Z coupe and convertible. Although it looks very 370Z, there are a few notable changes here. The nose has been updated with six new vents above the lower intake, while the fog lights have been replaced with... blank space.
