According to TV Guide, here are the challenges for the first two weeks of the 'Nationals' competition. Thanks for the tip grOOvealOOse
- 2/18/2010: The Nationals - The top nine crews from across the country compete against each other for the first time. Each will be assigned a hit song that will serve as inspiration for a hip-hop dance routine.
- 2/25/2010: Music Video Challenge -The eight remaining crews choreograph routines inspired by some of the hottest music videos.
Note that the number of crews in the shows drops from 9 to 8, even though there will be no time to vote. So, the February 18 show appears to be a sudden death round, with voting for the remaining crews beginning on that date.
