Here is what is confirmed. James Earl Jones will be doing the voice for Darth Vader for around 5 minutes. If you want to check this, search out some Star Wars fansite, a number of them should have this. It may not be 5 minutes, but it will only be a short viewing of Darth Vader in the end.

On Kas's setup of the possible plot.



Anakin and Amadila have kids (correct)

Anakin is found out (correct)

Anakin is banished from Jedi Order (good possibility)

Anakin makes contact with sith lord (Palpatine does not go to Anakin as Sidious, that much is for certain. Only Count Dooku will know of Sidious, Anakin will only know Palpatine... for Palpatine to reveal himself to be a Sith right away would wear down his trust with Anakin.)

Anakin has fight with obi wan, and falls into the lavapit (Of course. That's the climax of the film)

Anakin joins sith lord (Yeah, Palpatine saves his ass through the darkside. A-la Freedon Nadd to Exar'Kun.)

Anakin kills Amidala, and tries to kill kids (This point doesn't make much sense to me. He already showed in the original trilogy some surprise to having kids. I mean, how else did he not know of Leia? If he did, he would've gone after her since she was in the Galactic Senate when it was still around.)

Obi-Wan hides kids. (Obi-Wan only truly hides Luke. Leia was taken in by Senator Organa.)

You hear the Emporer say... "Kill them all" (I'm not even going to comment on this... LOL)

YOu see Darth Vader sabering a Jedi (The Jedi Purge at the hand of Darth Vader doesn't happen right away, and not all Jedi were exterminated by Darth Vader. So this is iffy.)

Screen fades out. (I've never seen a Star Wars film end with a "fades out". The scenes tend to close off, not fade.)
