G37Beijing, this is a really good find. It's probably the closest thing to seeing what the 2010 will look like.
From looking at the other pics on that site, this is actually a sedan!

Not sure if this might equate to the sport front end in the us or the non-sport. Either way, it actually looks good as it gives it a similarly agressive front end like the coupe.
The interior pics seem like they could fit with the changes that were mentioned. Minor changes primarily to the center arm rest area. I thought the release said something about changes to the center stack but it looks about the same here (if they were referring to the area around the radio, etc.).
