Ricoh GR3: No rocker switch, less dust intrusion?

[emerson]

There's some speculation on Ricoh fora that the elimination of the rocker switch is intended to mitigate potential dust intrusion. Interesting idea, though I do not know with any certainty that this is the location where dust is drawn as the lens extends, as claimed. But this seems to me to be a plausible cause for altering the design.

All in all, it might be a fair trade-off, if true.

Some folks point to the bellows effect of the retractable lens; others point to the rocket switch or other gaps around controls/switches... who's to say what is or isn't to blame for dust intrusion? At least the ultrasonic dust removal will help in the majority of cases - sometimes you get a large fleck that just won't budge, but at least the dust removal should be able to be activated at will to combat it.
