That is right - you cannot tell if a 4 month old pup is a show prospect. Even though it is a repeat breeding that does not guarantee that this litter will turn out the same. You have hopes, but no guarantee. I have seen repeat breedings and sometimes it works and sometimes they do not turn out the same. I hope this person actually has champions they have finished. It sounds like they have picked the one for themself and another for the friend probably based on sex of puppies and weight. We look at the heads at his time, but only just looking and watching. You also must watch personality too. Without a strong outgoing personality it makes it hard to finish. So be sure to keep this in mind too.
You will have a better chance of getting something you are looking for if it is a 5-6 month old pup and still that is just hope. A pup can really fall apart even from 6 months to a year old. All of us breeders for show can only hope and wish until they reach their maturity without any problems.
I feel too that it is the dam that contibutes a lot too. You should be able to see the dam when you get there. They should have photos too of the dam or can takes some and send to you. Tell them you understand if she has been clipped down.
