Nobody "knows" anything about the next 7D, not a feature and not a release date. If you're under NDA with Canon you're not going to give it away I promise you. All we're doing here is speculation. We are speculating what the next 7D should be like. For fun. It's an 18MP sensor therefore we speculate it will increase like every new generation to 20 or 24. It does 8fps therefore we speculate the next step is 10 fps. It has an excellent 19 Point Af system sp we speculate it will get the next best in the line-up, the 61 point AF. We speculate of course it will get the new DPAF technology as the 70D, and of course better video features, and new 5D3 menus and other upgrades. However this ALL just speculation, no one actually knows what the 7D will be like apart from Canon itself.
To sum up the hard inside-information we've got so far:
-20.2MP as in 70D, and 20.2MP with New Sensor Tech. and 24MP with or without New Sensor Tech.
-10 fps, and 12fps
-61 point AF, and 65 point AF
-It will have Wifi and GPS, and not
-It will have the 1D top plate, and not
-It will have an integrated grip, and not
-It will be announced on Sep. 5th. and 15th.
You get my point. It's all user speculation of what the next step from the 7D should/could be, and some of the speculation will probably materialize in the final product. Only Canon knows what will be in the next 7D, and if contains any surprises.
Some things like new sensor technology for example are not to be speculated, that's why we did not know a thing about the DPAF in the 70D until the day it was announced.
If you study the market, the company history, and the competition, you can make pretty accurate speculations about future products. I for example know the next 7D will be called the 7D mk II based on the company's history. I know it will have a higher pixel count, and 10 frames per second, and the Dual-pixel AF, and the new 5D3 menus... and the announcement in the world's largest camera show is also probably true These are what we can accurately expect but anything innovative or specific is not possible to be speculated. We're just having fun.
