I wonder if the only thing holding the portable unit back from using the full 768 MHz or 900+ MHz is simply the battery?
Because man it would be awesome to have a model some day that could full clock in portable mode and go even higher in docked mode, the only issue is you'd be stuck with a bunch of Switch owners who have the old model, but maybe the work-around could be that they have to buy a larger battery pak to play certain games.
