Another interview with a Nikon executive (Nabuaki Sasagaki, General Manager, Marketing Department of Nikon Imaging Japan) by Focus-Numerique. His answer on the Nikon D90 replacement (Google translated):
"Before the D90 there was no demand for a video recording feature on DSLR. Since it became a standard and we receive many requests for improvements. It is therefore very likely that such an update to intervene in the near future. And a simple firmware update may not be possible ... The white balance also will be part of the improvements."
His response on a new EVIL camera from Nikon:
"Of course, we study these new concepts. But we can not disclose any of our choices for the moment."
And finally his answer on whether Nikon will release "more affordable" lenses soon:
"Yes, you can count on it!"
