I believe Nikon will announce the Nikon D4, AF-S 85mm f/1.8G lens and probably the Nikon WT-5 wireless transmitter tonight, around midnight EST. I think the January 10th date on the leaked Wells Fargo article was a mistake.
Here is another Nikon event in Kuala Lumpur:
Nikon Product launch at Berjaya Times Square Hotel, Jalan Imbi, Kuala Lumpur at 12:30pm.
