Sony has told developers that the PlayStation 3 will soon have the ability to save games in the cloud. They’ve named it simply Online Saving. Soon you’ll be able to save your games and access them from anywhere. You won’t have to carry your PS3 to your friends house anymore.
It isn’t free however. This cloud service will only be available to PlayStation Plus subscribers. If you are among those who subscribe to this, you can expect to get Online Saving with the upcoming 3.60 firmware update.
