Reviewed.com has their camera staff at CP+ in Tokyo and have taken some time to write a pretty extensive preview of the Canon PowerShot G1 X II. On the surface, they appear very positive about the camera. Keep in mind, these thoughts are without actual real world image samples and usability tests.
Some thoughts from reviewed.com
“The retooled Canon PowerShot G1 X Mark II is a clear shot at the Sony Cyber-shot RX100 II—a camera that currently enjoys an undisputed reign atop the pocket cam hierarchy. And in some key specs, the Canon is a superior offering. Its lens is both brighter and has more reach, and the sensor's a lot bigger, too. All of that ought to translate to higher image quality, especially in low light.”
