Back to FX / DX, during a moment of boredom I looked for D3X rumours and found this interesting video.

It was an assumption of mine that the 'X' would have a DX but it seems this rumour has it as FX sensor with a 17M odd FX crop.
Other interesting rumoured spec's its the max shutter of 1/2000 and sync speed of 1/1000 and ISO 12-640 without any boost. It would appear the D3X rumoured here would be definitely a studio camera.
If true, its not for me!
