There appears to be some confusion at the SB estore. The Advanced Digital Audio Center appears to have gone through a name change and is now "Rio Central".

Also, one of the pages is now listing the price as $1299.95, but when you go to order it the price is still $1499.95

Edit:

Hmm, looks like someone spotted the error. I reloaded the page and the price is back to $1499.95 again...
