GameTrailers taped some gameplay video of Counter-Strike: Global Offensive on the map that defines the series, Dust.
Dust is built exactly like the classic Dust map that's been on Counter-Strike since the day one. Keep in mind, this is off-camera footage, so it has the usual issues of recording video off a screen.
