I found on Nikon rumor a rumor about the imminent release of the Nikon D3s which is supposed to shoot 1080/24p. Apparently the expected announcement date is October 15th, 2009. Let's hope that Nikon is getting it right this time.
Here is what I found so far:
-Nikon D3s with ISO 200-12800 (D3 was with ISO 200-6400).
-New ISO range HI-3 at 102,400 ISO.
-12.1 mp FX sensor (same as the D3, but tweaked).
-D-movie 1080 with 24 fps.
