Seriously?! Dude, if he’s been let loose to the media then that’s literally his job to do exactly that!
The 370 sold pitifully (in comparison) as it was the wrong car at the wrong price point. Why would Nissan be desperate to follow it up any time soon? They either need to go cheaper (no chance), faster (nope, that’s GTR territory) or more premium (and get buyers out of a TT, Porsche or maybe Alpine?!). So, so unlikely on all counts.
Maybe a Z replacement will come at some point. Maybe not. This just isn’t any kind of story though, it’s not confirming a damn thing other than someone at some point has shoved a sketch for a new car under his nose. Which ain’t gonna be a surprise to anyone, that will happen to him daily.
