Be sure to redeem your early access code asap : SWTOR Discussions

Apparently SWTOR announced that early access for pre orders starts the 15th of December. However they also said its going to be staggered over 5 days and your early access can start up to 5 days early based on when you redeem your code. So either its as soon as you redeem you can get in or they are going to be doing waves. Just a little tip for players.

Glad I got mine an hour after pre orders were announced.

Well you are pretty safe then if its based on the release time which im going to assume it is.
