The 7D being a flagship?
Why spend so much time on sticking a label on these products?
The 7D is just what it is, with exactly the features that it has! Discussing the "flagship" or "pro" labels doesn't help anybody because it's completely irrelevant, it's not as if the camera changes because it gets assigned an arbitrary label.
Let's at least speculate about the constellation of the product line-up, or about specifications of non-existing cameras, anything is more interesting than these labels!
To go on a journey you have to have directions. Directions are useless unless you know where you are.
So whether the 7D is indeed a flagship product is important and it will detirmine the marketing direction of its replacement
You can observe that, following the 7D, the xxD line was devaluated slightly, but that with the 650D the trend was reversed by giving an xxxD some features from the xxD line, and can therefore speculate on whether the new 70D will reach high enough to also succeed the 7D, or whether it means that the 7D2 will reach even higher. Now tell me how putting the "flagship" label on the 7D, or not, helps; this is a sincere question, I just fail to see it.
If you read the original post you will see that it was suggested that the 7D was the 'flagship' If this is true and Canon replace it with something else then there is a marketing issue.
Personally it is not my understanding that the 7D was a flagship - just the top of the prosumer range. If this is true then I believe there are fewer issues in replacing it with an updated model labelled 70D (again top of the prosumer range) - allowing Canon greater freedom with the technology inside the '7DII'
