Obviously the Nikon D3x images were leaked on purpose. You can almost tell that someone was monitoring NR and 45 minutes after my post, the images were removed. And then the Nikon Pro magazine release the next day... this is already a "standard procedure" by many companies.
Expect all Nikon web sites to go down for a short time on November 30th at midnight (US Eastern time), and this will put an end to the D3x rumor mill.
I would say D40/D40x/D60 is next in line to be updated. D40x is already discontinued in many stores and D40/D60 went down in price significantly (D40 goes for $409.95, D60 for $532.39). My prediction - January 2009. Live view is a must and video would be a logical consequence. What will be the new model number? D60x? D65? D10? We will know soon...
I also started getting tips about a new Nikon SB-700 flash.
Lenses? This is the toughest one to figure out.
We will have to wait a bit longer for the D400 (maybe mid 2009) and D800 (late 2009) and let's don't forget the Nikon MX.
...and next time when I say that I am 90% sure - believe me 🙂
