I don't think the announcement will be Sorcerers. I just looked through the latest "December Disney HELLO" email that came today.
Sorcerers was listed as its own little feature in the newsletter:
It then links to the article quoted earlier in this thread.
And then later on, down near the bottom:
As it specifically says "Disney Parks" and "for you to enjoy in 2012" I'm going to go out on a limb and hazard a guess that they're bringing back the "get in for free on your birthday" promotion. Or they'll take a cue from Universal's Super Bowl promo a couple years ago and give out free tickets to the first 50,000/100,000/whatever-number people who register for the promotion...
