Its what I would put a small sum of money on.
Have a look at this image it is taken from itunes and the detail is in this article
Here also is a comment from this article that I just noticed
"Looks like a docked eBook device. Remember folks, years ago, just before the iPhone rumors were abound, there was a fairly reliable report that Apple had begun to purchase the rights to a considerable number of books. With multi-touch, a more book shaped iPhone with a larger (7”?) screen and Amazon Kindle like content distribution system, they would have a killer device. Form factor and content is everything folks."
