Q was told no Nikon D700 replacement until 2011
Quesabesde writes that according to "unofficial sources", there won't be a Nikon D700 replacement until 2011. You can read the computer-translation as well. It also mentions the possibility of a new non-D700-related DSLR at/by Photokina and a G11-type of a competitor.
We obviously don't know who the "unofficial sources" are, it could be Nikon itself wanting to send an off-the-record message to its users.
Nevertheless, the sudden disappearance of the D700 body-only has a certain oddity to it. It's not like everyone decided to buy the Nikon D700 on Easter Sunday or dpreview posted a glowing review and everyone ran out to buy the camera and retailers sold out just like that. As usual, time will tell...
