With how much people love to take apart the new ____ from Apple and study it, it would have been found already, so I doubt that is the case. I think that bluetooth and a few other abilities would be a good move for a Tuesday launch (that’ today by the way) for Apple, a revolutionary new iPod (like the full widescreen thing) would more likely come at the Developer’s conference I’d think. I’ve been wrong before though.
I do expect the MacBooks to come out today though… they aren’t a secret at all, and it’s just a matter of time before the website changes. I’m going to push to get one at work.
