Once again, evolutionary improvements on an already good Nikon consumer series body leave competitors behind in many metrics.. and price.
One of these is on my xmas list. 2 more if it performs really well.
They seem to have changed the grip to body spacing a little from previous models, I hope it's still comfortable to hold like the 5100/5200.
WiFi and GPS abilities, + 1080P at 60fps will be features useful to some.
