It appears that Anakin’s force ghost in the upcoming novel, “Shadow of the Sith” will be the Hayden Christensen version.
“Standing between himself and the wraiths was another figure—a man in flowing pale robes, his back to Luke, his head hidden under a voluminous hood… When the lightning flashed, Luke could see the nine solid wraiths through the form of the man who stood between them and their quarry… The blue figure lifted his hood back to reveal the strong, sharp face of a young man, his gaze intense beneath a furrowed brow that was bisected by straight, vertical scar. His thick hair was shoulder-length and had a slight wave to it. Anakin Skywalker reached out his hand.”
