Email from regarding TOR early access:
Early Game Access* will begin on December 13th at 7:00AM EST, 2011 and ends on December 19th, 2011 at 10:01PM EST. During this time, we will be emailing invitations to join Early Game Access based on the order in which you redeemed your Pre-Order Code. Pre-load the game client now, so you’re ready to play when your Early Game Access invitation arrives. Note that download time can vary and may take awhile.
I had guessed the early access would have started around the 15th but it seems it opens up on the 13th, a Tuesday night.
Again, it’ll be a staggered entry based on when you pre-ordered.
