(re: Codename: Iceman Sequel)
The Codename: Iceman sequal was mentioned in a catalog that came with King’s Quest 5, I think. I actually wrote a letter to Sierra customer service asking about it, and the reply was something along the line of “we decided against it in the short term, but in the long term we may change our minds”. And Codename: Iceman came out quite a few years before Jim Walls left Sierra over the PQ squabbles.
