The ability to transfer data is bittersweet, however, since it doesn't appear to support backups. As described in Nintendo's FAQ, you'll need both systems to transfer data from one to another, and the only option available moves all profile data including saves and eShop purchases from one system to the next.

Other new features include profile icons with characters from Super Mario Odyssey (just ahead of its release on October 27th) and The Legend of Zelda: Breath of the Wild, as well as the option to pre-order and pre-download games in Nintendo's eShop on the Switch (again, just in time for Super Mario Odyssey). The News Feed has a new look, and if you're in a group of local users it can easily update everyone's system software to the latest version.
