Ask HN: iPad File Sync?

I don't have a blog or anywhere else to put this, so I ask you: do you think the iPad will allow App Store apps to sync files with iTunes? I ask this because iBooks (an app from the App Store) allows you to "add free ePub titles to iTunes and sync them to the iBooks app on your iPad" (http://www.apple.com/ipad/features/ibooks.html). Apple does have crazy restrictions, but I don't think they would use an API nobody else is allowed to touch. I know this sounds fanboyish/rumorish, but it could open up a lot of app possibilities, such as letting users sync and view content Apple doesn't like.
