I don't know why anyone keeps talking about double bass, the second pedal is clearly positioned as a hi-hat pedal, not a second bass pedal. It's at an angle to the bass pedal and positioned directly under the hi-hat, exactly like A FRICKING HI-HAT PEDAL. It's not a bass pedal.
So the new DM kit is: left crash, hi-hat with pedal, snare, three toms, right crash. Pretty damn close to a real kit, and will be pretty different to play, especially if the hi-hat pedal is charted (can't quite tell from the video, but I assume it is). Craziness.
Now to figure out how we convince the Vancouver arcades to stump up for a machine. I guess we'll have to commit to a few hundred games each at $2 a shot
