I haven't seen a review of the p7700 yet.
Frankly the last few Nikon flagship compacts have been left trailing firmly in the G series dust.
NEVER buy a camera on spec sheet alone. Megapickles etc only tell about the third of the story!
10MP is enough. what is needed is the lens to be faster and the sensor to be bigger. One of the primary shortcoming of advance point and shoot like these is low light performance. Most of the times, I want to attend a party with just a point and shoot. There are also a lot of times where you need something light or the situation doesn't permit to bring DSLR. For that I really like G1X except it's too pricey and priced like a DSLR already. I hope this G15 turns into a better performer.
See this? Our family is just going to the supermarket. Of course, I didn't bring a DSLR and tripod but suddenly I have this good opportunity to take a nice display of light. Sure it maybe nice but I hope I can get a little bit better picture than this. This was taken with G11, ISO 100, F/4, 1s. I looked for a fairly flat surface and took this picture. This is in Suria Mall, KLCC, Malaysia.
