Considering that the RX100 is also cheaper... easy win for Sony, as far as I am concerned.
but we are not comparing the G1X with anything here, we were discussing the G15 rumours. The G1X was an anomaly the X indicating it was an eXperiment. Now there's an EOS M the G1X has no place between the G15 (whatever it might eventually turn out to be) and the EOS M.
Sure the RX100 gets rave reviews but it has a short zoom and no vari angle screen apart from being pricey for what it is. If the new G15 doesn't have a vari-angled screen the Nikon P7700 might be a better bet once it's sensor and lens have been tested.
One more day of nail biting.
