Not to me I have a D700, and have no intention of moving down to a body with functions in the menus rather than on the body itself. The fx bodies like D700 and D3x are aimed at a different market - the people who want to get the D7k are not the same people who want to get the D700. The people who buy the fx bodies, buy them for a different purpose and are willing to live with the weight of that camera because it gives them functionalities which are missing from the prosumer cameras. Would I ever want to get a D7k as a second camera, possibly. But then I would go for something like the D300s because the body would still be familiar to me after the D700. I think that the people who wanted to get the fx body, will still buy it. The people who wanted to get the D90, may get the D7k. In the end, it's all about the pictures, and how comfortable that camera feels in your hand and whether it allows you to shoot how you want to shoot. I'm sure that if I had a D90 now, I would think about getting a D7k, but if I had my heart set on a D700, I would not even look at a D7k. It's all about what you want I'm sure that the D7k is a fine camera and many people will buy it and love it.
