Based on my extensive reading and cross referencing of various online rumour sites, I can say that the D2X will be
Full Frame/1.3 FOV/1.5 FOV
CCD/CMOS/LBCAST sensor, possibly 2 x D2H sensors side by side
A hybrid film/digital, or not
The imaging chip will be user upgradable/upgradable by Nikon/gold encrusted platinum with ruby microlenses.
will use the CAM2000 AF module, or not
$7000/$4500/$3000
Essentially the same body style as the D2H (except if it is the F6 digital/film hybrid...)
Available:
At the olympics
September
October
Spring
2006
That about sums it up

BTW: those who claim to actually know, claim that there are some D2X prototypes disquised as D2H's in the hands of a select group of heavily NDA-restricted pro photographers, and that they will be used at the Olympics.
I have seen a comment that, if the D2X is going to be "debuted" at the Olympics, Nikon will need to get press kits out to the various camera magazines in the next week or so to allow coverage in the "Olympic" issues of the magazines.
I still think Photokina is the best bet...
