So, as I'm writing this post, I actually logged into subscription center and found some cool stuff. http://subscription.autodesk.com
Log into subscription and go to this link: https://autodesk.subscribenet.com/control/adsk/index
You can download AutoCAD & AutoCAD Architecture 2010 right now. That will put you 45 minutes ahead of tomorrow's actual release date. You can check back there daily to see if you can download Revit products. Some of them are listed now, but the files are available for download.
This year, for the first time, Autodesk® Subscription customers will have the option of downloading their product upgrades directly from Subscription Center. As soon as our new 2010 products are released, they will be available for download on Subscription Center, before DVDs are shipped.
As products release throughout the year, subscription customers will learn about this great new download option through auto-fulfillment email notifications and directly on Subscription Center. Customers who choose the download can also request a DVD.
Customers will be able to download both 2009 and 2010 products. Each year, we will add the latest product versions but continue to make previous versions available to meet customer needs, creating an online “Product Library” for our subscription customers.
We’re delighted to offer this new service to subscription customers at no cost. To gauge our customers’ preference, we are asking subscription customers in Canada, Korea, and the UK to go to Subscription Center and choose how they prefer to receive their new product – download, DVD, or both.
Action: To learn more about this offering, access the FAQ on the Subscription Center login page. Look for the “Speed up Download” promotion box on the right side of the page (which I don't actually see, but you might).
