I expect those are the real press pics, as Tine said. They don't look anything like chops or pictures I've seen, and the lighting and stuff looks entirely believable. The colouring reminds me of the leaked pics of the M6 we saw a while ago, and also the Audi S8 pics that were leaked recently.

Anyhow, I actually like the non-M Z4's facelift. It makes the front look a little less 'low' and featureless. Not bad. OTOH, I don't like the Z4M's front bumper, lines and vents in all directions. The rear of it looks quite good though.
