The X Factor (USA): Judges House

I believe I know at least a couple of people who made it through to the Judges' houses! Based on a news articles and the newest promo of The X Factor.
Although the News article came out even before Season 2 started, it was posted talking about the contestants. Most of this publisher's predictions were correct for who got through to the Judges' houses.

If you look at the commercial closely, zooming either in or out, you can recognize some of the contestants.
