It's been years since I read the Argonian Compendium, and I can't find it on The Imperial Library any more, but Argonians are one of the least fleshed-out in official lore of the races as I recall. The Argonian Compendium actually contains significant chunks of "off-the-record" chats with devs rather than official information. They are, however, definitely not warm-blooded, and most likely not fully reptilian.

Re: Do Argonians lay eggs? [Re: Vireyar]

Or because an Argonian says that he didn't hatch yesterday ... *cough* Just a figure of speech, I suppose.
Which is why I said "Perhaps it is both, as necessity demands."
Never underestimate the adaptability of Argonians, or, more specifically, the power of the Hist to allow Argonians to adapt.
I wouldn't expect to hear an Argonian born in Skyrim (or on Solstheim, for that matter) mention being hatched. Nor would I expect to hear more transient Argonians (say, members of a small, nomadic tribe) speak about laying eggs. However, in warmer climates, in places with established, stable, and permanent communities, you would likely see a great number of eggs.
This means that not only can Argonians live in Skyrim, but can be born there.
Thanks!
Sounds encouraging.
*addendum to my earlier post: I can understand it, but I will not be too happy if they are cut.
