And what of those who haven't played KOTOR 1 and have no save file? What if a person has multiple save files? What if that save file contained cheats? I'm a little skeptical to the whole "survey" thing also, but using a save file doesn't seem like it would work out too well, in my opinion.
I also think that some type of romance in KOTOR II is pretty much a given. I just hope the romances are a lot more intricate than the romances were in KOTOR I, even if they're not between your character and another. They do sometimes help to make you have more of a connection and care more (or hate in some cases) about the other characters when there's a romance involved. As for seeing a kiss in first person... that would be a little awkard. It might give the same impression if someone were to make out with a window with someone staring at them from the other side. It would probably work otherwise (in a cinematic, maybe), though.
