Update: Nintendo has now released the following statement:
The vast majority of Nintendo Switch games will support Save Data Cloud backup. However, in certain games this feature would make it possible to, for example, regain items that had been traded to other players, or revert to a higher online multiplayer ranking that had been lost. To ensure fair play, Save Data Cloud backup may not be enabled for such games. To ensure that Save Data Cloud backups cannot be used to unfairly affect online multiplayer rankings, the feature will not be enabled in Splatoon 2.
The warning message has also been removed from a number of game pages.
Original article: Despite a rumour all existing releases on the Nintendo Switch would technically support cloud saves when the online service launched for the system later this month, new information found on various game pages of the Nintendo website suggests there'll be multiple titles without this feature.
According to Game Informer, there are clear messages at the bottom of certain Switch pages, indicating which games will not support cloud saves. Below is the exact warning on display:
Nintendo Switch Online membership (sold separately) and Nintendo Account required for online play. This game does not support Save Data Cloud backup. Not available in all countries. Internet access required for online features.
This message has been located on the game pages for the first-party titles Pokémon Let's Go, Pikachu! and Let's Go, Eevee! and Splatoon 2. Third-party games Dark Souls: Remastered, Dead Cells, FIFA 19 and NBA 2K19 also display this warning. As Game Informer points out, all of the above-mentioned third-party titles support cloud saves on PlayStation and Xbox.
This news stems from the discovery Switch game cases would state whether or not cloud saves were supported.
