I always think the D300/s will be the last of semi pro DX Nikon bodies. The next next one will be a semi pro FX like a D700 or D800 but with a crop DX mode for DX users to slowly blend into full framers.
juz imagine a D7000 with 51 AF point, D300s built quality and ergonomics, ok la up the MP say, 22? Dual slot, CF and SD. Not bad rite? Anyway if Nikon does come up with another FX so soon, then FX will be too mainstream. If they really do come out with another FX camera, not on par with the D800/700, what will happen to the DX cameras?
