Btw: "EOS 7D Mark II, EOS 70D & 700D" ... only one consumer body? There are supposed to be at least two xxxd releases a year, what's up Canon? :->
No, Canon has only ever released on xxxD camera per year (T1i, T2i, T3i, now T4i)...and then every couple of years they update their entry camera, which is an xxxxD (XS, T3)
You can see the timeline here: http://en.wikipedia.org/wiki/Comparison_of_Canon_EOS_digital_cameras
Canon would just replace the xxxxD lineup with the EOS-M camera/lenses.
I think this will be the reality. I can't imagine anyone who would buy a T3 at this point when the EOS-M is similarly spec'd and priced. I think the xxxxD line is dead.
Also wouldn't surprise me if in 3 years or so, the xxxD line goes by the wayside too.
