I'd love to be able to farm, but I don't really expect more than Oblivion, which was pretty much only the harvesting part. (There are tons of farms in Oblivion you can visit to do that, though.)
Well, we have actual smithing, leathermaking, among other crafting abilities, I wouldn't be surprised at all if we had actual farming. It was done with mods in Oblivion, and Bethesda seems to be taking many ideas from mods for Skyrim.
