As rumored and becoming obvious over the past few days, Canon announced its PowerShot G15 enthusiast’s camera today – a replacement for the G12 but skipping the G13 and G14 product names for various reasons of their own.
Instead of the G12 being the end of a product line, I now suspect that the G1X will be a one-off model line because Canon's enthusiast compact product line seems to be getting crowded. Perhaps Canon is floating trial balloons to see which way the market winds are blowing.
I also suspect that the G15 probably was spec'd and designed very quickly in response to the moderate reception given the G1X. With the exception of a faster lens, the G15 appears to be a modest update to the G12. Since I still have my G12 and have added the G1X, I don’t feel particularly inclined to purchase a G15.
More later as I read and learn about the G15.
