Correct me if I'm wrong but that wisdom of crowds theory would only work for a predetermined number, not for something yet to be established. The average guess of a crowd will normally be more accurate than an individual's.
Here's how he did it (IMO)
Filmed with a few separate groups until one group predicted 3 or more numbers in one of the draws to give the illusion of this prediction system working. Probability suggests this would happen soon enough.
He then got this group to choose more numbers – which he conveniently didn't show to anyone until after the draw. The whole point of a prediction is that you show it before the event.
The film itself was clearly split screen filming. The moving camera effect was to throw you off the scent – either applied live, or was two shots filmed separately from the same sequence of movements. The shot is only still for about 2 seconds before he walks over to his numbers (once the draw has all been completed), which is when it stops being split screen, and reverts back to a single shot.
The numbers weren't predicted – they were simply placed there once the draw had been made. If he could really predict this, he would have shown his prediction ten minutes before the draw.
