Having given presentations myself, I think all this means is that the presentation slides etc (e.g., a Power Point presentation) must be uploaded to the web site by Jan 4 at the latest. Everyone will have to wait until Jan 8 to actually hear the presentations by Dr. John Commissiong and Dr. Rubinsfeld that the presentation slides will accompany.
There are of course insiders talking about all this I have no doubt. But most people and corporate attendees will have to wait for the main course on Jan 8.
