There are some similar design philosophies, but there is most likely no meaningful relationship between the two from an ancestry perspective.It's a similar layout and feature set. It has a news feed, list of recently played games, shortcuts to user settings, system settings and eShop. That's not similar to how the 3DS worked or was laid out. It's also incredibly small, similar to how the Gamepad OS was and the code name was similar to QuickStart which is what the Gamepad OS was called.
