So in the E3 gameplay we see "your heavy armor has increased" which makes light armor almost confirmed.

Are the 18 skills:
- 1 handed
- 2 handed
- block
- archery
- heavy armor
- smithing

- mage we know

- sneak
- security
- speechcraft
- mercantile
- light armor
- alchemy

Or is something merged with a sixth unanounced combat skill?
