Strangely enough, I've found myself processing skin less! Same touch ups, like cloning out the odd spot or wrinkle, but only when needed. I don't soften skin really, I used to with the D90 - but prefer not to in general. I find hair, clothes textures, eyes to be sharper - but not the skin. I'm not so technically minded as to know why exactly

maybe because skin isn't exactly sharp to begin with? or something ... And maybe also because I am improving, especially with lighting, and getting my exposures better with less need for post processing. I think I was over sharpening in the past, and then having to soften skin to counter.
Unless you're using a macro lens on it, and getting in real close - I wouldn't worry. The detail is incredible, but I've not found that it over sharpens skin, if that helps?
