There's a teaser ad over at the Nikon website, suggesting a replacement for the D70s will be announced in mid-August.
It'll be a 10.2MP body, which is similar to the D200. I'd been giving some good thought to getting a D200 but now that this has appeared it will be a good idea to hang back and see what all of the fuss is about.
With any luck it'll be what the D70 was to the D100 -- more or less the same camera in a cheaper (lighter) shell. I've read some people suggesting that a few corners will be cut, and I doubt that the AF will be upgraded as Nikon did with the D70. It should make an interesting camera and will no doubt make a few D200 owners a little annoyed ;)
