ohh ok.
so both still in production.
but anyway, imo the DX ones dont need that much upgrading, compared to FX which needs much better glass in order to get corner sharpness etc...guess thats why the 17-35 got discon.
i dont think the 24-70 needs replacing tho

A prosumer constant aperture zoom and a couple of primes would be nice for the hobbyist actually.
In fact, the high end market is all FX already. If they're going to cannibalize their lower end DX with the Nikon 1, I'd be pretty sure that the mid end will start shifting upwards in response as an upgrade path from the Nikon 1. Look at the D7000, when it came out it practically rivalled or even some ways superceded the D300s in specs, and startled the heck out of Canon when their 60D came out. That there is proof that Nikon would be quite happy to get the jump on their competitor in each target market, hence the FX shift.
Then, I also think it's quite hard to continuously iterate the D300s in DX form. What more can you throw in? Improved video, a better AF system? When the D7000 already is close to the D300s in specs, the differentiator then becomes either number of pixels, or upping the size of the sensor.
Also, I believe that the target market for the D700s and the D800 is different in terms of the amount they are willing to pay and their requirements. Going through the bythom poll and the nikonrumors polls, you can see that the feedback is split in half. Half want the high res D800, some just want a D700s. It is quite possible to just keep a slightly improved D700 with the D3s sensor, and improvements from the D800. Simply by keeping the pricing where it currently is, the gaps in the lineup are filled. The people who want 36mpix will go for the D800, the people who don't need it go for the D700s. And I also think that simple economics can come into play. Sell more of the lower end camera and get higher profit instead of selling less of the higher end one. The current D700 demand is proof, even though the camera is considered last generation.
Well...thats just my 2c why the there would be a cheaper FX body.
