It's been thrown around here and there, but now we have news on the most likely cable network it will land on. Looks like it's not TBS or any of their other sisters stations (like TruTV), as well as The Hub.
GSN will most likely be producing The Impostor. This is a game show where a contestant is introduced to a family consisting of five or more members (mother, father, children, grandparents), and has to figure out which one of the individuals is not actually part of the family. The casting call was listed here earlier in March, and is now closed.
I can easily see this landing on GSN. The top prize is $25,000, fit for GSN's budget. The network is also trying to attempt "out of studio based game shows". This is a family game show, just what GSN is looking for, trying not to revert back to some of the 2011 originals.
We won't know if The Impostor will have a possibility of making it to air until the GSN upfronts are released next Tuesday. Even from there, The Impostor could still not make it to television. We will have to wait and see for the finalized news soon.
