Based on the above quasi-official source (a sweepstakes promotion involving Amtrak trips - and corresponding blackout dates), it seems that in 2012-13, blackout dates will include the following dates before June 30:
February 17, 2012
February 20, 2012
April 5-6, 2012
April 9, 2012
May 25, 2012
Now, it appears that they're going to stick to the practice of blacking out the front end of Memorial Day weekend but not the back end. They've also replaced Easter Sunday with Maundy Thursday (aka Holy Thursday).
