They only taped a limited number of episodes, and I believe they've run through all those by now. Based on the fact that they're not running reruns (as they do with every other Food Network program(, I wouldn't look for the show to come back.
IMO, the first two rounds were fatally flawed - too slow moving and uninteresting. The general question round and final round weren't bad, but by then it was too late. Seems to me that the most successful quiz shows have a single, consistent, fast-paced format throughout most of the show, with the final round treated as an exclamation mark.
