Quoted from Nikonrumor:
A new DSLR positioned somewhere between the D610 and the D810 models.
Here are the expected specifications:
•24MP full frame sensor
•Tilting LCD screen
•Wi-Fi support
•Expeed 4 imaging processor
•Very light body (probably similar to the D610 and Df, maybe even lighter)
•
Priced around $2,500 (the current Nikon FX camera price points are - D610: $1,896.95, Df: $2,746.95, D810: $3,296.95, D4s: $6,496.95)
•Potential announcement at the end of August or early September
•No idea on the model name - it could be D620, D750 or something completely different
•The probability rating on this rumor is currently at 70% - I am pretty confident that this camera is coming, I am just not sure about the detailed specifications.
