As can be seen on this article on ain't it cool news, Lucas intends on altering several of the original movies by adding a few scenes (and presumably making more money off the new versions). So here is my guess as to the nature of the added scene in ep 6: During the ending celebrations, when Luke looks and sees the glowing Anakin, Obi Wan, and Yoda, he will see Anakin morph into the young (Hayden Christensen) Anakin, and then he'll be joined by a young Padme. They'll hold hands, Obi Wan & Yoda will appear younger as well, and then the closing credits will run.
