While GSN has at least two renewable originals right now, those two being The Chase and Skin Wars for sure, there has not been any sign of renewal for any of these shows yet. The last time a GSN original got renewed was Idiotest last October.
It looks like GSN wants to renew their originals in bulk via one press release, like they did with The Chase and It Takes a Church last summer. This time around, it could be more than two originals.
An exception with Skin Wars could occur: There may be a renewal during the Skin Wars finale this Wednesday, like last year. During last September's Skin Wars reunion (that aired after the actual finale; there is no reunion this season), RuPaul announced that there would be a second season of Skin Wars. Without any press release, there may be a casting call and/or announcement for a third season of Skin Wars on air this week.
