Activision also released these demonstration shots, along with appropriate descriptions, to show off the game:

Boosting in Machu Picchu: Players initiate boost by giving the Wii controller a quick move forward.

Hangtime in San Francisco: Players can tilt the Wii controller to change the direction coming off of sticker slap.

Just look at those models! If the game is anywhere near as fun as they make it to be, I’m gonna be the first in line for Wii!
