Digital Rev has a new, suggestive article entitled The Nikon D400 & D750 Revealed or Just Viral Marketing? While the title would lead you to believe that there’s been some kind of leak or specific promotion on the D400 and/or D750 (neither of which have been confirmed by Nikon), the post appears to simply be Digital Rev’s take on recent rumors, along with some fancy mockups and spec/wish list.
I’ve had several emails to this article, suggesting that it’s a leak of some sort. Upon second glance, it seems to just be a racy title with no evidence of either of these cameras being revealed by Nikon, or evidence of viral marketing on behalf of Nikon. In essence, it appears to simply be speculation.
