I'm in the same situation as several of you. I have a collection of DX lenses that do what I need them to do. I couldn't afford to switch to Canon because I didn't just go to the camera store and buy a camera and a set of lenses. I started out with a camera and a basic lens and then added lenses as I could afford them. I don't have the kind of money it would take to buy a Canon setup like what I have.
FX has both advantages and disadvantages for me, but one of the disadvantages is the cost. Even the lowest end DX camera is considerably more expensive than the best FX. And, I'd have to replace all my FX lenses. They would work on a DX camera, but who whats to go back to 5 megapixel pictures, especially after spending that much on a DX casmera. Not to mention that, AFAIK, there's no DX equivalent to my go-to lens, my 18-200mm.
It sure would help us a lot if Nikon would give at least some hints of what they plan to offer. But they have to be careful with that. A company I worked for years ago announced a new product about six months before it came out, and it killed the sales of what was at the time the current product.
