UPDATE: The Nikon D3X has been officially unveiled. See details of the Nikon D3X Announcement here.
The rumors surrounding the Nikon D3X have been stirring quite a bit over the last few days. See here and here for examples. Thom Hogan has stepped out with some more solid dates based on supposedly more solid rumors.
Current rumors out of Japan have Nikon introducing the D90, D3x, plus lenses, in the second week of June. I’m tightening my D90 (or whatever they decide to call it) prediction date to between May 12th and June 16th.
