If you're into high-end compact cameras, you'll have another one to choose from soon -- we just don't know how soon. Interestingly, Canon has revealed that it is working on the PowerShot G3 X, but the company wasn't willing to share many details about it. What we do know, however, is that the G3 X point-and-shoot camera is slated to feature a large (for its size) 1-inch CMOS sensor with a 24-600mm (35mm-equivalent), 25x optical zoom lens. The company says this model will fit right between the G1 X Mark II and G7 X, as it looks to expand its offerings for people who want a well-specced, premium compact shooter. Canon's calling this a "product development announcement" for now, but we'll know more about the G3 X at the CP+ imaging event in Yokohama, Japan, next week.
