Speculation is Craig Ferguson (the Scottish guy from Drew Carey) is getting the gig. Bit of a strange choice in my opinion. I expected them to go with D.L. Hughley or Michael Ian Black (as mentioned in the link).
That being said though, I did catch Ferguson a couple times in his "trial nights" and he is pretty funny. Much different than Kilborn (who frankly seemed too full of himself most of the time).
