That would utterly weird if Nikon blends the D90/D300 line, BUT, if they do, it makes room for a $1700 FX model, allows the D800 to have some room, and then of course there's that 50% price gap to the D3s. . .
So are we thinking:
1. D90+D300s=D8000 with all the features at $1299; 16MP.
2. Consumer-FX at $1696 (where D300s used to be); no AF motor, reduced AF points. 12MP.
3. Semi-Pro-FX at $2699; AF motor, same AF points as D700. 14MP.
4. Pro-FX; dual cards, AF motor, expanded AF points (think D4). 16 MP.
A little bit of wishful thinking there on the $1696 FX camera, maybe $2000-2500. I bet the sensor alone costs $1200, which would lead to razor thin profit margins on such a camera. The semi pro will likely come in a around $3000, like the D700 did. I also doubt Nikon will remove the AF motor from the bodies, of such cameras, until there are no AF-D models in the lineup.
