Steve, I got the same email. I wonder if maybe they will do it at a different time next year. They already have the One Pocket and 10 Ball events during that time. While it sure would be a good time to do it with so many players already there, perhaps a fourth event is just too much if they've added 8 Ball now. The league tournament only runs two weeks though that shouldn't matter since not many of the league players seem to want to walk down the hall to support the pro events. Maybe the 8 Ball event will generate more interest.
The National BCAPL tournament is moving to July for 2013. I'm assuming the pro events will be held in conjunction with this. Interestingly, the Dragon 14.1 event is also in July, or at least was this year. Maybe that has something to do with it as well.
I don't see either an 8 Ball or 14.1 Open currently on the list of events on the website, but they don't have any 2013 events listed yet.
