I did not know that, do you know when?
I use a recorder (Time Warner version of TiVO) so I don't keep schedules.
If you are asking when WPT is moving, I guess at the end of the season. I see promo stuff already appearing on GSN, I don't think this is a good move, not as many people get GSN as they do the Travel Channel, but maybe Travel Channel dumped them, I don't know.
