It appears the Nikon 1 GPS and the EVF attach to the Nikon 1 V3 through the same accessory port and there is no way to attach the GPS to the EVF or vice versa. I hope this isn't true but it's pretty silly to pay $1200 for a Nikon 1 V3 without a GPS built-in or GPV via a WiFi app like the Olympus EM-10 and the Fuji X-T1.
I'd consider this camera with the EVF for $600 or less. $1200 no thanks!
I still love my Nikon 1 V1 which does have the ability to have an EVF and GPS attached simultaneously!
Finally, the super 70-300 zoom sounds awesome but again is overpriced at $999; again I'd buy it for $600 or less!
21st century cameras are social and on the internet and awesome-ized by software and sensors
