Nikon has announcements scheduled for the week of August 16th (I believe there are two days of announcements: the 17th and the 18th, but I'm never invited so I don't know for sure, I'm getting those dates second hand). As Nikon Rumors has reported, we're going to get the fall Coolpix line (including a new P camera), a low-end DSLR (the D3000 replacement), and some lenses. Conspicuously missing from that list are the D90 replacement, the D700 replacement, and the mirrorless camera. I sort of doubt Nikon would make another announcement prior to Photokina (historically, Nikon doesn't do big announcements that close together--it overtaxes their subsidiaries, amongst other things).
So either he or Nikonrumors thinks no D90 replacement will be announced.
Cheers
