P7100 is, from what I've read, a fine camera. If you can get it for a good price, and it does all the things you're looking for in a camera, then sure, go for it!
Waiting a while for the P7700 prices to drop: I have no idea how quickly Nikon prices usually drop, but if you can afford to wait a while, that's always a good idea. With the P7100 you have a very capable camera in your hand, so there's no rush... and who knows what else might be released in the mean time
