Here is another random thought. If we are going to, obviously, be able to name our characters, what are all the NPC going to call us? Will you go through the entire game and only hear yourself being refered to as "Sir", "M'Lord", or "Hey you"? Somehow I don't think that "PwnMaster L33towitz" was recorded in their audio sessions.
Bioware:"Okay Frank just 30,000 more combos to record. You need another glass of water?"
Frank: "No I'm good. Ahem here we go. Corpsecamper, Sarlaccmyballs, teabag4u, yourmom, yourdad, yourgrandma, yourgrandpa, vaderraider, vaderraider2, vaderraider 3, vaderraider 4....."
Seriously I think they are probably writing the dialog much like they did KOTOR 1 before plot elements revealed who you were pre-amnesia. I mean I named my guy Jago Bonita when I played recently (because the World Cup was on) and it didn't pose a problem. They will probably refer to you by rank often, sir, ma'am, or simply you _race_ scum.
