Kotaku has learned that, earlier today, Sony informed developers of a new feature for the PlayStation 3: the ability to save games in the "cloud".
Cloud storage means that, rather than keeping your save game data on your PlayStation 3's hard drive, it's instead saved remotely to a server that Sony runs. The advantage of this is that not only does it save the user space on their hard drive, but since it's tied to a PlayStation Network account, it can be pulled down to different consoles whenever and wherever the user desires.
First rumoured all the way back in 2009, there is of course a catch: it'll only be made available to PlayStation Plus subscribers, not the great unwashed. Actually, there are two catches: Sony bundled the announcement with the clause that, because saving games to the cloud "will allow save data with the copy prohibited attribute to be copied into the online storage", developers are able to opt out and bar their games from using it should there be a concern.
Sony will call the process "Online Saving", and it'll be made available as part of the PS3's upcoming 3.60 firmware update.
