I can't seem to find the official confirmation but according to several blogs from poker players and 2+2 it appears that the show High Stakes Poker will tape it's fifth season in September and air on GSN in February. Originally the option for HSP wasn't renewed and the World Poker Tour was also let go on the Game show Network. It looked bleak for poker on TV as the only shows that were being produced was a time buy in Poker After Dark airing at 2:30AM, The World Series on ESPN and the Heads Up challenge that airs once a year on NBC.
PAD did fill the void of the lack of cash game play by airing a week of cash games last week but it's regular format is a 6 person sit and go. I think that cash is ultimately more interesting to watch and play than a tournament where increasing blinds create variance and dictate action. I suppose the TV execs want the all in action but I think if done well with a good commentator cash games can make for a more interesting show.
Why GSN had the change of heart? I have no idea, but nonetheless, I'm glad it will be back. I will also personally hunt down males aged 18-35 with neilson boxes and make them watch the show. I should've done this years ago for Arrested Development and Firefly.
