Earlier Cisco dropped the band information, and now we have the bag information too!
The bag this year is a first that I can recall, it is a 2 in 1 backpack convertible into a duffle bag!  The strap pictured on the front of the image below is detachable, yet when attached the bag can be used as a duffle!

In case you are wondering what  Backpack convertible into a duffle bag is, I found some good pics over on eBags of one.
