Not to blow the horn of the Team I work with most of the time....
But...
One of the best sources for initial scouting is the SOAP site. Team 108's Soap Program has numerous videos of matches from this years event. I would take a look and when you get the Championship at Epcot check them out for everything they do have.
The site can be found at:

Enjoy.
