At that point I think we got confirmations from more than 20 different sources that there will be some kind of announcement next week (received reports were mainly for the Nikon D90).
Here is what Thom Hogan has to say about August 27th (read the whole article to get a feeling of what he is trying to communicate - this is my own interpretation of his words):
- introduction of Nikon D90 with the 18-105 lens
- update of Nikon D3 (maybe D3s)
- maybe two or three lenses
- low chance of introducing a third DSLR
