Of course it needs to operate the shutter ... all electronic shutters as yet do not have the control and resolution possible with a mechanical shutter. And like with most SLRs, the shutter regulation, aperture control and mirror are a linked mechanical operation so there's no good way to cycle the shutter without also cycling the others.
On Olympus bodies, the auto-bracket feature and the "capture three on one shutter press" are implemented separately: you have to turn on auto-bracket AND drive mode to achieve this automation. I find this very useful in some situations (say when using a flash unit to allow time for recycling). If a camera has independently, electronically controlled shutter, mirror and aperture operation, then an option to do auto-bracketing on one press cycling only the shutter as quickly as possible would be a nice feature for use when appropriate. I don't believe it's possible with the design of today's Pentax (or any other) SLR bodies.
