Based on some info from an insider I expect availability by the end of July.
- According to the rumoured specs I plan to upgrade from D800e to D810 for a higher resolution screen and 6 fps at full resolution. For macro shooting both better LCD and speed increase are quite important...
- Further more I hope there will be a real "silent mode" as well. Until now the silent modes both in my D3s(which I sold-regret...) and D800 are a joke...
- AF evolution like D4 -> D4s is welcome.
- 1 stop gain in iso performance might be interesting but would not be a reason for upgrade to me...
