Over at Macworld Expo San Francisco, the mob is forming outside Moscone West to get into the keynote. Not surprisingly, the Apple Store web site is down for scheduled maintenance.

The web site has historically gone down for maintenance in years past when Apple was about to release new products. This, combined with various "There's something in the air" banners hanging around the expo have led to speculation.

It's anyone's guess as to what's around the corner at this point, but feel free to throw in your ideas over in the comments and forums.
