Here are the rumored specs for the canon 1DsMk4
32(or 38)mp full frame sensor
same body as current 1DsMk3
Announcement maybe Spring 2010 or September Photokina 2010.
If this is true what are the chances Nikon announces a D3XS with video? Could be the whole D3S/1Dmk4 "joint" announcement all over again?
