Speculation: Will Microsoft's ZuneHD Include an eBook Reader?

There’s a lot of interesting speculation about the rumored Microsoft ZuneHD which resembles an iPod touch with a large multi-touch touch screen. One speculation we have not seen about it so far, however, is whether or not it will be an ebook reader to compete with the Kindle or, at least, the Kindle iPhone app. Why would I think it might be an ebook reader if no one else does? A friend recently pointed out (tweeted) that the old Microsoft Reader, and ebook app nearly a decade old now seems to be in a revival phase.
