What I reported back in July, now has a probability of 99%: Nikon has scheduled multiple press events across Europe for August 19th, 2010.
I am still a bit puzzled about the Coolpix cameras announcement that is suppose to be on August 17th, 2010. In the past, Nikon aways announced the p&s line one week before or after the DSLR products. Maybe this time they are trying to combine both announcements in one press event.
The big question, to which I don't have an answer yet, is whether the Nikon D90 replacement will be announced on that date as well.
