In KOTOR 3 I'd like to see things that point towards images of the future. Meaning beginnings of work on making republic soldiers super. To point towards clone troopers. Beginnings of technology in laser developement on destroying cities and work towards expanding that to destroying planets.
Basically signs and images the characters see in the game that elude towards the current star wars movies. And the ability to effect that future. Since in KOTR 1 you were able to effect the future so much I think if Bioware does that game they should revive that theme in KOTOR 3. I think it should be of next gen technology and of course Revan should return.
