Seems that Electronic Arts is going through a rebrand of their Origin accounts program. Some users of the service are reporting that they’ve received e-mails about an account branding change.

The e-mail says that “in the coming weeks your Origin Account will be renamed to an EA Account” but otherwise nothing else is expected to be changed – just the branding and the design. Account owners are reassured that “Your Account identity, preferences, and order history will remain unchanged.
You will continue to use this account and the same login credentials to access all EA games, web sites, and services, including Origin.”

No reasons have been given for the change of account naming, but it’s possible that EA are seeking to try and brand things under one umbrella to improve association between all the parts of their business. The changes will happen automatically without any users needing to do anything, and EA hope that the transition will go smoothly.
