iTunes 4.9 on the net

According to PT over at MAKE:Blog, "iTunes/4.9 (Macintosh; N; PPC)" has started showing up in user agent strings for podcast download logs. If Apple is testing it in the wild, I can't imagine a release should be too far behind. I have high hopes for this release making many people's lives a lot simpler. My question, though, is this: will it allow for uploads as well as downloads? Will we be able to record casts on our iPods with external mikes and have an option to easily sync them to our blogs, or at least our .Mac public folders, when we plug into our computers the way we can with iPhoto albums? That would be a nifty feature.
