Even the grille is in line with its lineage. The s30 had a massive grille, it's just that it was broken up by the bumper:
But, and this is also part of the s30 story, a lot of those cars ultimately had the bumper removed by their owners as part of body kit modifications or otherwise. See for example...
So I don't think the grille bothers me very much. But as I say, we'll need to see it in real life. I personally wouldn't be buying a launch version, I'll wait to see what they do with the NISMO.
I'm also very interested to see the curb weight. The 370z actually got lower, shorter, wider, and most importantly slightly lighter than the 350z. If they can get it to around 3000 lbs for the Nismo I'll be very interested.
