DOF is determined by three things, and three things only:

Notice that sensor size is not included in the three DOF determinants.

Repeat as often as required for it to sink in.
The sensor size, since it determines FOV, directly affects the photographer\'s actions when framing a subject. As I just explained, in order to shoot \"the same shot\" the photographer either increases focal length or or moves closer to the subject, both of which decrease the DOF of the shot.
So, indirectly, sensor size affects DOF.
Anyone who can still argue this point is a gearhead who is forgetting the most important part of photography; You.
