The European Nintendo Switch website has been updated to give you detailed information about the handheld, dock, Joy-Cons and more. It’s basically an overview of how the system works and the many features that the console has. Interestingly, it states that the system will only use USB 2.0 at launch but these will be updated to USB 3.0 for faster charging. There’s also information on how the Home Menu works. You can view it all here.
Launches with USB 2.0 support, but USB 3.0 support will be added in a future update.
