I just heard that we will be seeing a new 70D and 7D mkII!!!
Here is the timeline I was told
The 7D and 60D will remain current
year 2015 still current
year 2018 new sensor tech announced
year 2025 70D and 7D mkII receive a long awaited upgrade and have digic VI processors and an 18MP hybrid sensor with phase AF for continuos focus in video mode! Also, the power of the new processor will enable 1 full stop better high iso when shooting jpeg.
seems about right to me...
