Finaly we got some news about the long awaited 70D. Somehow it is silly to talk about what features will be included and what not, because we just can't know; but it is fun anyway.
I personaly belive that it will not have the SL1 sensor in it. Even if Canon was very slow with sensor development recently, and are putting almost 4 year old sensors in new cameras. That works quite well for low end cameras, but I do not think canon will pull this stunt for the 70D. The 60D was already a little dissapointment after the 50D. On the other hand the 70D needs quite some more features than the 700D to justify its price. And then there is Nikon and Sony; Canon needs to catch up.
I think It will be a new sensor, like rumored at the beginning of the year. GPS and WiFi will also be onboard, especially WiFi will become standard on cameras. It would not expect to much from the AF system and the body. These will be points where the 7DII will score, so Canon will hold back on these features. Thats okay with me, just give me a very sensitiv center AF-Point, and plastic for the body is nowadays very good.
Looking forward to the announcment.
