Found and quoted from a pretty reliable source, japanese magazine (CAPA) seems to have posted specs for 2 Canon cameras (70D and 3D!) to be revealed very soon along with the other mirrorless models slated for also this year. I reckon we’ll know more on or after June 8, 2012 when the new Rebel is supposed to be launched.
22MP and DIGIC5+
Canon EOS 3D
30+ megapixels, 1D-class body
Dual Digic5+ processors for 6 FPS
61-point AF system, major functions same as 1DX
Equipped with flash (or speedlite transmitter)
