I think that we know already that he comes out with his whole torso from looking at the pics of him getting shocked at the end of ROTJ.... my guess is that he will loose another arm... but not both because I cant see the fighting going after Anakin looses both arms and I cant see Obi Wan pushing an armless anakin around. Also I would guess that if he loses his legs it will be from them burning in the lava rather than ObiWan choping them off... but who knows....only GL .....and the entire staff of LucasFilm, ILM ect.
Most of you have probably seen this but for those who havnt... The Injuries of Darth Vader - http://www.theforce.net/swtc/injuries.html
I guess its totally possible but I just dont see something happening to Anakin in Ep 3 that would leave him as just a head... I think it would be kinda cheesy too. And if Greivous is just a half a head and spine and all droid body than that should be his thing and Vader should not be the same.. I like the Idea of him mangled together of body and machine.
ok, but seeing these pics, i think we all can at least reject the one arm/one leg theory... 😛
personally, i think we will see a mangled anakin body pulled out of the volcano, but then a scene where the body is....cleaned up. a very brief but gorey scene of anakin with all body parts removed, and he will be hooked up to the iron lung.
as for the pics, i cant help but see a machine from the jaw down.
even his neck is partly or wholely mechanical.
Luke did save a machine!! With his fathers brain. Thats what functioned the machine. I agree with you PVS look and the shocking clips, clearly even his neck is machine. He will have the torso hanging there but as PVS said, its burnt and useless flesh. I believe there will be almost nothing to salvage except Anakins mind, Which is really all the emporer needs.
