Well, considering that there will be less skills, I't seems quite improbable, but who knows, mybe its related to (atletics if it's present in game).
Well that's the thing, alot of people think to get something done in the game you have to have a skill. It could easily be a perk. There is no need to go Daggerfall way and add in worthless 95% of the time skills like Impish or centaurion. I'd knock myself out if I saw a "No falling off cliff" skill <_<
But yeah, if that really is an in game mechanic, it could easily be an athletics perk, which is what makes the new game so amazing, so much more customization than just slopping skills into the game.
