I guess I need to point out the difference from a "rumor" at CR and a person making guesses. CR doesn't just sit around and make guesses. They have contacts with people inside Canon who may not be directly involved with a particular camera, but who come into regular contact with those who do. And such people in the workplace tend to talk about things they're doing on occasion. When that happens, they pass it on to CR and it becomes a "rumor". CR rates those rumors based on the source's previous history of accuracy.
So a CR1 is a rumor from an unfamiliar source or a source without a proven track record of being accuracy. A CR2 is coming from a person who has access to such information and also has a track history of getting it right.
Random speculation isn't given a CR value at all. So for example, today there are two posts. Once is about a possible 35+MP camera at Photokina. The other is that the 7DII won't have wifi. The first has no CR value at all. The post states clearly that a source for someone else reported this information. They don't know the source, it wasn't directly given to them by the source, so it wasn't assigned a CR value. The second is a CR2. This "good source" also stated it would have Eos-1 build quality. Then the author states that their opinion is that this may mean that it's a large MP camera.
There is a considerable difference between a source and an opinion. Does this mean the source is always right? No. But the quality of the source matters. Reading some of the comments I have flashbacks of debates about scientific topics with people who throw the word "theory" around as if it is the same thing as conjecture or guessing.
Everything I came to a conclusion on was based on a mixture of actual rumors and my own guesswork. But let me sort those out here:
7D replacement exists - multiple CR2 source confirmations
7D replacement is an even nicer build quality and more 1D like - multiple CR2 source confirmations
7DII announcement in the next month - multiple CRII source confirmations
24MP improved sensor - multiple CRII source confirmations
10 fps - guess work and a couple CR1s and CR2s that conflict between 9 and 12 fps
gps - CR1
wifi - CR1 with conflicting CR2 stating it won't be there and my guess that it's a little late to not have wifi
integrated grip - OLD CR2 and CR1 which may have changed over time along with my guesswork with the CR2 mention of a new battery
radio control of flash - pure guesswork
dual card slots - CR1 and CR2 - different sources
7DII name - up in the air
As with anything, the more specific you get, the less accurate you are. But a couple things which have multiple CR2 values from multiple sources all say that a replacement is imminent and that it will have a more 1D like build quality, more MP, and better noise and ISO.
I am serious....and don't call me Shirley.
