OK, not to put a damper on my own post, but did anyone notice how the wallpaper isn't full screen. If you zoom in on the top and bottom, you can notice there's a slight gap between the top/bottom of the wallpaper and the top/bottom bezels. It's more noticeable on the top. It makes the curved corners look like they're slightly cut off. From the leaked videos of working units, we know this is not the case with the display. So this still may be an actual press rendering but with sloppy editing, or maybe a fake. We'll find out soon enough.
It could just be an early non-press-ready render. I don't believe Evan has ever posted something that turned out to be a fake.
