It keeps cumming - first rumors for 2 new Canons on
5D Split? 5D X & 5D Mark III [CR1] « Canon Rumors
45 MPix With a pixel size similar to the power shot G1X....
this would mean a pixel level even smaller than the Nikon D800
on the DPreview site there are already image samples of the G1x- i would say- this by 4 in one shot could be impressive.
Canon is filling a potential Photobag with sharp lenses for it- the new 24-70L II seems to be pretty good.
This will be an interesting year !
