Update: Turns out this particular shot is a fake.

From a Chinese forum (via Nikon Watch)
See the prism/popup flash. That is unlike anything before it. The strap also has D700 strap (though you can't see the rest of the zeros)..the D70 strap did NOT look like this so this is also a key sign.
We wait for July 1st.
