Say goodbye to the Playstation Network, and get ready to embrace the Sony Entertainment Network. On February 8, 2012, Sony will be changing the name of our “beloved” PSN to the SEN, or Sony Entertainment Network.
The change only applies to the name, however; the service itself will stay exactly the same. This name change is Sony’s attempt to complete their goal of “establishing a global comprehensive network platform of services across games, movies, music and more, all accessible from one convenient account.” In other words, they’re just making it easier to log in to all of the various Sony accounts. Thankfully, there will be no need to change your PSN ID; the only thing you have to worry about is a system update so you can agree to a new Terms of Service agreement.
You should be getting an e-mail soon from Sony giving more details. So don’t be scared when you receive a random message from them; it’s not another hack attack.
