I've been raging pretty hard on this subject, my Khajiit is left out too. Got a thread started complaining about it in my sig.
Yeah, I think it would do Bethesda good if they start going out and try to improve their relations with the Argonian and Khajiit fans. Though I thought I've been hearing that they got rid of the vampire fangs for Argonian and Khajiit vampires myself. If they've still got the fangs from vanilla, then I think it would be nice if they at least fixed a lot of the visual glitches that occur with them, though, like them clipping through the face between the nose and upper lip. If only vampires were allowed to change their face in order to remove this graphical error. I still think their eyes as a vampire could be a lot better. It would have been cool if they had gotten glowing orange or red eyes (probably the orange, to match the other vampires) as a vampire instead of them getting the yellow eyes with the red pupil, which is okay, but not really what I picture their eyes looking like as a vampire. I think they should have it so the Khajiit don't get paler fur as well, though I already mentioned that.
Like I said (and many others, I'm sure) before, it would actually be pretty cool if the eye color, skin tone and appearance of fangs were determined by blood hunger, but I don't really see this happening until at least TES VI. It would solve a lot of problems people have with vampires and their visual changes.
