I like that you are trying to confirm skills, but I would like sources please
The first Archery, One Handed, Two Handed, Block, Heavy Armor, Light Armor, Smithing, Enchant, Alter, Conjure, Restore, Destruct, Illusion are all confirmed via the Skills menu during the G4TV demo. http://www.g4tv.com/videos/53441/the-elder-scrolls-v-skyrim-e3-gameplay-demo/?quality=hd
Sneak can be confirmed from another E3 demo. The character is 'sneaking' as the icon suggests. http://www.youtube.com/watch?v=K9hJMxw126A
Alchemy can be confirmed in the same demos, via the Nirnroot "Unknown Effects" menu, implying that is for alchemy. But just to prove even more... you can see it on the whiteboard during the Bethesda tour. http://www.youtube.com/watch?v=L5zVawg-J-w
The point is to speculate on the other skills... so asking for sources is moronic
