I see that a lot of sources are getting very excited with the belief that Canon are going to launch a new 7D in the first week of September.
Apparently Amazon in the US is now showing the 7D as 'Discontinued' . One thing I read states, "A new Canon patent points to combining Phase AF from the sensor with conventional Phase AF for better burst performance" and "7D2 rumours are getting a bit of a bump - only to be expected with the suspected announcement less than a month away. No WiFi and 24+MP both suggested."
Let's see what transpires.
