Some people seem to be seeing recurring armour pieces in some screenshots that are layered over different pieces each time, but it could just be a reused or "BETA default" sort of thing. No Im not searching for the thread for you. "Baldric"
The thread you are referring to is http://www.gamesas.com/index.php?/topic/1166731-extensive-armor-layering-options/.
As for my two cents: I believe we will have greater customization options. While the pics could be placeholders or beta shots, I'd like to think that Beth heard the constant griping on these forums about lack of armor layering. Personally, I'd want:
boots (just one slot)
gauntlets (left and right)
pauldrons (left and right)
chest piece
baldric/s
belt
helmet
greaves/fauld
capes/cloaks/robes
Additionally, I think on Light Armor, you should be able to wear clothes underneath. If I'm wearing a fauld, it should follow that I would need to wear some type of lower body garment (leather pants, etc). If I'm wearing a leather jerkin, fur armor or chainmail, I'll again need clothing underneath. To go along with this, I think the enchantment capabilities of light armor/clothing should be lessened. For heavy armor, you can't wear clothing underneath (not that you couldn't in real life, but that clothing would serve no function other than comfort) but the enchantment of the armor is much higher.
And those are my hasitly thought-out two cents.
