Today GSN will unveil the 2014-15 upfronts. We already know that American Bible Challenge will premiere May 22nd at 8pm Eastern. With this upfront, the status on such originals including The Chase, Skin Wars and It Takes a Church will be announced with premiere dates and a potential Season 3 for The Chase. We are expected no word on Mind of a Man due to extremely sagging ratings.
So far, I have not heard much. There's definitely a third season of The Chase brewing, which was due a while ago, along with the premiere date of American Bible Challenge. Otherwise, no great proposed game shows are in the works. I have heard that a show from the upfronts last year is carried into this year (The Imposter? Dance Rivals?) We'll have to wait and see.
Remember, like the examples given here, just because a show is listed does not mean it will make it to air.
