Honestly, without some Context your page doesn't tell me much. I can't use Google to translate what the Data represents since it is written in the image, not as text. From the description I guess the line is monthly sales and the bars are change compared to the previous year? And red is Canon, yellow Nikon and blue Sony, obviously.
The only relevant trend I see is the change in the lines from September to October. Two go slightly down, one goes up dramatically...
But apart from silly observations like that, it's too early and too little to make much of a Statement about the effect of the new Cameras on the companies success as far as I'm concerned.
