Given that the previous thread, based on a false rumor, has received over 150 replies, I thought I'd start a new thread to clarify this. Batali did not quit Iron Chef America. In fact, they aired a new IFA featuring Mario last night.
Here is a link to the article in which Batali emphatically states that these rumors are "Not True!"
"I’m taping two episodes of Iron Chef America in a few weeks. I’m the best Iron Chef, why would I quit? And why would I threaten the network? Molto Mario’s been out of production for two-and-a-half years. [Reruns still air weekly.] We have a fine relationship."
This was a big relief for me. Batali is my favorite Iron Chef, and his departure would have been a real loss.
