Here's an update for customers who have pre-ordered Star Wars: The Old Republic that was scheduled to be released on December 20, 2011. Because beta access ends at 11:59 p.m. Eastern Time on December 19, 2011, we've decided to ship the game early to customers starting December 15, 2011.
Quoted from Amazon US.
So please stop telling us this is EGA to reward people who ordered early. This is nothing of the sort, all you are doing is running a prelaunch beta and using the EGA as a cover for this.
