IMHO, I was kind of hoping for a better storyline... I mean, not that I liked where the first KOTOR was, but the way HIG put it, it seems like it's just right before KOTOR, but with the same themes of characters and such, which would kind of suck. That and if Revan came back, Revan would either have to be dark or light, which kind of messes with KOTOR's ending a bit.
Now if they flat out did something during the Mandolorian Wars or sommat and dropped the Revan part, that would be neat, although I'd rather see progression in the story rather than a prequel.
