It has been featured a few times that diablo 3 does have weapon enchants. I am curious about how you get these enchants? I have not heard about the ability to take up professions. My guess is that they are either drops or something you buy from a merchant. The cost of which will not be easy I presume.

Is there any confirmation?

Item crafting and/or augmentation isn't something we've discussed/revealed yet. I think it's obvious there will be some ability to change an item after you've picked it up off the ground, but what that will actually entail is a secret to be revealed later.
