PSN Accounts Changing To SEN Accounts Soon
It's nothing more than a cosmetic change for PlayStation Network users, but soon you will have a Sony Entertainment Network Account instead.
You may have to scroll down and ignore the text of a new user agreement once the change occurs, but other than that everything will likely stay the same.
According to an e-mail being sent out to PlayStation Network users, the change is being put into effect to, "get closer to [Sony's] goal of establishing a global comprehensive network platform of services across games, movies, music and more, all accessible from one convenient account."
If you haven't gotten an e-mail alerting you to the change already, you should be getting one soon.
