Sony announced today that tomorrow the PS3 system will receive an update (V3.60) that will enable Playstation Plus users to store up to 150MB of save games to Sony’s very own cloud allowing you to access them on ANY PS3 that you log into with the same PSN ID. This means you can now continue your favourite game at a friends house or in a different room without having to do any annoying transfers of files.
Most games will be compatible with this new storage option right away but they promise to continue updates later on.
These new features will be accessed through the XMB and allow you to save to the cloud and access them remotely.
Look for the update available March 10th on your PS3’s or turn on the Auto-Update feature from Playstation Plus and it’ll be ready for you when you wake up.
