It’s rumour time!
According to a thread on NeoGAF, the entire Nintendo Switch SDK documents were leaked on 4chan and “realisable sources from the scene” state the leak to be of the real thing, but even then it’s no guarantee. What is interesting though is real or not, the leak contains mention of save data transfers and a guest login feature being considered and so thanks to a separate thread on NeoGAF, we’re going to share what was said:
* * * * *
Save Data Transfers:
“In the future, we plan to provide a feature to transfer account save data among multiple consoles. As a result, there is the possibility that user accounts with uninitialized account save data will be added. Note that your design must work without issue, even in this case.”
Guest Login:
“We are considering a feature in the future (tentative name: Guest Login) to access existing network service account information without linking to a user account. This feature would allow temporary access to the network service account linked to the Nintendo Account by logging in to the Nintendo Account within the application. This feature would, for example, make it possible to upload a character you have raised as online data and then use that data on a friend’s NX (without creating a user account).
We do not plan to provide this feature for the NX launch.”

With the documents now in the hand of various members of the public, don’t be surprised if more pieces of news/rumours get shared, but we only promise to post the good stuff ad none of the chaff.
