Well, we all know that there are 18 skills in Skyrim. They are still broken into the Combat/Magic/Stealth categories but that doesn't matter ar much in Skyrim. From information gathered from the GI Magazine, GI Articles and the Todd Howard Podcast, I can make a list of the skills that are confirmed and what category they are most likely to be in:

COMBAT:
One-Handed
Two-Handed
Smithing


MAGIC:
Illusion
Alteration
Destruction
Enchanting
Conjuration
Restoration

STEALTH:
Alchemy
Marksman
Sneak
Speechcraft

If I have missed any or if you (dis)agree with what categories I have put them in, feel free to dicuss below.

Okay. Sorry about that.

Nope, seems about right.
We also know that there will be Hand-to-Hand combat, so that might get it's own skill.

I guess they are aiming for large public friendly game...

In a way, the combat skills are ok (enables easier multi weapon uses, but in the other way, it's not diversed...

They are more diverse than in Oblivion due to perks. Note that there wasn't any differnece between two handed and one handed in Oblivion, and here the perks individualize the character even more as they specialize into specific weapon types.
