I found this, but I'm questioning the pics... doesn't look like anything change from the VE, (in the grille) but the tail lights and wheels look Pontiac ... and any reason why they would not be testing it in the states???

That is sooo not the production front fascia for the G8. Look at the alignment/panel gaps where the hood, front fascia, and headlight all meet. Notice the hood pin on the passengers' side. They probably need it just to keep the thing closed because the latch won't line up. Also, the headlight does not fit in its hole. At least this sort of confirms that the G8 will differ somewhat from the Commodore from the A-pillar forward.
