That there is no way to transfer save files from system to system is brutal on Nintendo's part. It's difficult to attribute it to something other than incompetence...
Writer Anthony John Agnello sent his system to Nintendo for repair, and not only did he report that the replacement system also had issues, the letter that came with the new system stated that Nintendo wasn’t able to move his saved games nor data to the new system. All that time spend on Breath of the Wild? Gone. Nintendo has confirmed to us that there is no way to move the files from one system to another, but the assumption was that Nintendo itself would be able to do so if you system were damaged.
That assumption turned out to be wrong.
