I own a D700, D300 and D200. I would recommend the D700 if you like to use lenses with a wide angle-of-view. The D7000 will be significantly lighter and somewhat smaller. Both have moisture/dust sealing. The D7000 has more megapixels. The D7000 uses a different AF system. Reviews claim the D7000 AF is performs as well as the D3/D700/system. I do know the D700/300 AF is superb. Nikon's RGB matrix metering is also useful for both metering accuracy and AF lock on with subjects in motion. The D7000 has a 100% finder while the D700 has a 95% finder. The D700 finder is bright and may be better than the D7000's as it is larger (but I don't know if this is so). Both bodies are compatible with ~98% of Nikons' AI, AIS, AF, AF-S lenses.
I think the choice is really about lens selection and subject matter. What lenses do you own and what lenses would you plan to buy? If my D300 was stolen, I would replace it with a D700 because of the type of photography I do. If my D700 was stolen I would just get another D700 immediately. The D700 will be replaced. But I would not wait. Even if the D700 replacement was announced next week, it would take months before you could get one... and it may cost more.
If you are leaning towards DX, and if low-light performance is not critical, I would think hard about a used D300 or D300S. If you can find a reliable source, the D300 is an excellent camera. It is about 1 to 1.5 stops noisier than the D700/7000. The D300 does not take movies.
