There was plenty of information about Canon replacing the G12 in the last few months, and now it's official with the coming of the G1X. [Update] It appears that the G1X is not a replacement, but a new line of camera.
Sorry for the short post guys, i'm flying out to Las Vegas (CES) today, but you can read more about it over at the B&H Article (click here).
Pricing expected to be around $799 can be found with more technical product specs at the pre-order page already live (click here).
