Damn, awesome! I am completely in shock they are showing the grille so early in development....it's almost in between first testing stages and FEP stage.

I think the shape, size and posiition of that new grille is pretty great
It also reminds me a lot of the 7er, with the long flat bonnet with bulges on the side, big grille and position of the lights...

The difference between the F10 and F01 is more or less the same as the difference between E38 and E39, and not E65 and E60. Frontlights and backlights will look more different though I suppose (hope).

These two cars breath the same design language as well:

E39:
