No probably not. Especially since the picture is of a monitor displaying a .psd file. Seems a little too sloppy to me though so it is still a little hard to tell. When I first saw the picture the title of the window was the first place I looked, if this picture was a fake you would assume they would make sure that you couldn’t see the title of the window the .psd file was in.

UPDATE: Gizmodo was asked to take the picture down which they say confirms this rumor (I’m still sceptical). However as you can see I still have the picture here until Apple tells me to take it down because I feel it is fair use for me to have it up.
