Thanks for all the wonderful comments.
To confirm you suspicions, yes we do have the "nerve to swerve" this year. Our gearboxes are powered by the Fisher Price and Drill motors, with Globe handling the steering.
Shifting Swerve Drive? The idea was talked about, but in the end we felt we wouldn't have the weight for it. Our gearbox mastermind, Ian Mackenzie may want to elaborate on this.
In regards to the pneumatic cylinder on the table, you are correct in that it was just lying on the table at the time of the picture. But, that is not to say we aren't using pneumatics on our drive system... You'll have to wait until the next teaser to see those.
Or, you could look very carefully at the following video clips. This is footage of our robot driving for the first time.
