The latest rumors suggest that Canon has a new camera announcement coming on April 23, 2013. While no specific details have leaked out at this point, the Canon 70D seems to be a very likely candidate.
The 70D has been rumored to be coming for several months now. The timing is also right to replace the 2.5 year old Canon 60D.
Previous rumors indicated that the 70D would feature the same 18MP CMOS sensor as is found in the Canon Rebel T5i, as well as a more robust build similar to the Canon 50D from a couple generations back.
