The game won't be out on Origin for another week, same as everywhere else. Also, the game will be available on Steam for the same price.

Btw, sometimes you can download the game before the official start. That means the game you download can sit on your drive for several days, and you can start playing it only when the game is unlocked by the client. That should help out people with slower DL speed to start the game at the same time as everyone else.
