Alright so there were several cool spoilerish props.
Sam's chip at the end.
The Tron light up figure, which I believe is based on the Rinzler figure you can buy now, though i cant remember if the lights were white and it would need a new head.
As well as the CLU figure that lit up. Hopefully they make this one soon...
The little silver adn gold cube things in Kevin's room that Clue aws playing with.
Also as seen in the trailers, Sam's room had one of the new Kevin light cycles, one white one black, and one of the old yellow Tomy light cycles.
