I agree completely, Bastila dead is not something I want to see in this game. I played through KotOR a number of times, some light and some dark, but the data that I will be inputting into KotOR2 will be from my light-side and Bastila romance ending, so of course I want to see Bastila alive, with Revan, and light.
Now, given all that, I do realize that this is their (Obsidian/LucasArts) story and ultimately it will be what they want it to be. I can only hope that our suggestions/requests are listened to or at the least considered, only if as briefly as one minuet discussion in a story meeting.
