"Expedition Unknown", which has a 8.4 out of 10 rating on IMDB, is still airing Season 2 episodes. The crew is on the road filming more episodes, what we can assume is for Season 3. One thing I noticed on this new season is we are seeing more and more of the crew members, which I know was a complaint from fans from the first season, so that's refreshing.
For those who somehow were still unaware, yes, "Destination Truth" was canceled back in 2014. Josh's contract ended with Syfy/NBC. Josh does not have the power to bring that show back and based on how well Travel Channel is treating his name/brand and his fans, I don't think it's a bad thing. I also doubt Syfy will ever bring "DT" back. We have the memories of that great show, as well as episodes on iTunes and Josh's book about filming the show :-)
