If it's the stuff about Party-members fighting each other and all the rest of that "well-known" stuff then yes, I know about those, but nothing on cut areas of Malachor, unless those areas were involved with the cut dialog.

You can actually see some of the cut areas of the Trayus academy in the game. Just head over to the Trayus Proving Grounds and walk as close as possible to the walls. After doing that, look at your map. You will see several bullet point markers in the black void outside of the map. One is a meditation chamber, another is a cell block. Using the reveal map cheat will show you even more of these bullet points. Another interesting thing to note is that if you check your map while in the main area of the Trayus Academy, you will notice that the doors to the Trayus Cresent are called "Entrance to Trayus Prison". This makes me think that the Trayus Cresent was originally the area where you found your party members, while the other path through the Trayus Proving Grounds would take you straight to Kreia. I base this on a cut peice of dialogue (which is still partially in the game) in which Kreia says to Lord Sion "When the exile enters Trayus academy he/she will be faced with a choice. One path will lead straight here to the Trayus Core, the other will lead him/her to his/her friends, though he/she will become weaker for it."
