imdb says:
Pressure from LucasArts to release the game in time for the Christmas season forced Obsidian (Developers) to abbreviate the ending. Things from the ending include:
* 1. Atton and Mira arguing whether or not to kill Kreia while she is meditating in the Trayas Core.
* 2. Kreia killing Handmaiden/Disciple.
* 3. Kreia killing Visas and Mira.
*4. Sion wounding Atton.
*5. Atton dying after talking to player.

By the way, Xard, how do you restore the cut content, 'cause if its downloadable I can't get it (no XBox live).
