I know a collector in Melbourne that has approx 90 of them and yes he was 1 of 3 or 4 people that collected $5k (from memory) with the winning predictor card.
a trader called "cardshowcase" has a few of them for sale at the moment, all starting at $400 each! if he had them, a richmond team set would cost a minimum of $3200!! and these are for cards that have no pic on them at all!
To be honest i've given up getting them, im thankful i suppose that there is no player image on the card or team logo, otherwise i dare say it would really annoy me not having them.
If i come across them then great! but im not losing sleep over it either.
