Has there been any news on the art book being sold seperately from the collector's edition? I've seen a couple pictures of the artwork pop up on websites such as Kotaku or IGN and I gotta say I'm hooked and I want to see more haha.

PS I know they're being sold on eBay but I'd prefer if I bought it from Bethesda, more money to the developers I say!
PSS sorry if someone brought this up already

I'd still say eBay, as money for art books won't make a massive difference to Bethesda's humongous profit from selling the actual game. I haven't heard anything about selling separately, and I've no idea what happened with the Morrowind/Oblivion books, so I'm afraid I can't help you otherwise.
