you're right lawn...the capability will be there, but it's possible that the all mechanical button will come out in a later batch after the vv switch.
EDIT: actually, i don't know anymore....i've heard the vv was in the switch, but since vv was removable, a later released mechanical switch could take its place...but i've also heard that the switch is entirely mechanical, like all previous GG stuff, and imeo's currently waiting on the electronics which will not be in the switch. so who knows, but the all mechanical option will eventually be there for sure.
