There's a pic from Ain't it Cool News that shows the shot where Luke sees the ghosts of Yoda, Obi-wan and Anakin. There's been long rumors that Lucas was going to change the Anakin from Sabestian Shaw to Hayden Christensen. AICN claims this picture is legit. It shows Hayden as Anakin, next to the old Yoda and Obi-wan... this makes no sense, and I don't buy any of that "he turned to the Dark Side when he was young" thing. I'm a bit skeptical about the legitimacy of the pic, but here it is anyway, in case "vanishes" later on from the site.
