Interestingly, I have the BS tech version, and I almost thought it seemed to have a very tiny bit of camber as well (not enough to even be visible, but just barely enough to feel on a hard surface). I believe it is supposed to be flat between the bindings and rockered a bit towards the tips, but mine appears to be basically just flat (even compared to my son's Ride board that has LowRize rocker which is quite subtle). I did confirm that it has BS tech with a straight edge though.
A few pics (forgive the ugly, rusty straightedge):
