According to the Online Schedule, Beat The Chefs is gone completely. It looks like all of it's airings have been replaced by The Pyramid except on Sunday where 5th Grader takes it's slots back.
Aren't there a few more episodes of this? The show wasn't doing THAT bad... I feel like it will keep one slot (at least) on the schedule. We'll have to wait for updated PDF's or a change to the online schedule to see for sure.
