Their latest Nikon rumor is from David D. Busch's Amazon Blog:
"Veteran DSLR guidebook writer David Busch is hinting at his Amazon blog of a new Nikon camera (DSLR?) coming soon. He says, quote:
My guidebooks for the D700, D3, and a soon-to-be announced additional camera...
So that seems to suggest that there is at least one more impact Nikon camera coming up. We can't tell for sure whether this refers to a DSLR, an impact compact, or perhaps something else. The text says "camera", not "DSLR", so we cannot jump to conclusions.
And of course there could be more than one coming, but the author is planning a book about one of them."
