Obsidian have stated that they want a more fulfilling ending than KotOR, i think it was MCA who said that they want a similar ending like in the Fallouts.
Maybe she's just hiding her Jedi capabilities as much as possible in order to avoid getting the Sith's attention. It would fit to the story pretty well, considering how the Jedi are being hunted in TSL.
I'm not entirely sure, but i think it was mentioned in a interview that KotOR II will leave much room for a sequel. If true, then KotOR III is not an impossibility anymore.
I don't think they will bring back characters from the old Krath in TSL. Mainly because most of them died in the war. What I am thinking is the survivors and the descendants of the old Krath have remained in the shadows on Onderon, slowing regaining their former strength and waiting until the time was right to exact their revenge. Revan and Malak's war would have presented the right opportunity to strike since the Republic would be too busy to respond to what seems like a small rebellion on Onderon. Now the reason I bring up Freedon Nadd is because he is the one who passed the ancient Sith teachings on to the Krath. He taught them how to control the Dark side and Sith magic
I'm choosing the side that offers fast vessels, chicks with big t1ts, free booze and every other stimulant that there is, lots of credits and other fortunes, and yeah, i want to be the hero too.
IIRC, she even contradicted herself on that point too, saying that she didn't have time/was unable to perform battle meditation back on the Endar Spire.
