Oh well basically the same sensor again.
Canon has an investment in the 18 MP APS-C sensor. It appears to be a sweet spot for them. They are then segmenting the market (marketing 101) by changing functions with in the body (AF, buffer size, focus points, ...).
Sensor advances will come in the high end cameras - not the low end cameras. Creating a new sensor is expensive so to get maximum economic return Canon will first release it in high end bodies with higher margins. This given consumer the incentive to purchase a more expensive camera
Oh I understand well how Canon is really a conservative company and they are more responsible to their stakeholders. The company understands the market better than the competition. How else can they be a market leader? Not to say Canon makes poor products but a release like the 700d really has no reason to exist IMHO but to squeeze that sensor for everything it's worth while offering subtle changes. The low-end DSLR's are their bread and butter. Some people that are starting into photography probably rely on reviews and eventually the lack on innovation specially on the Rebel line or xxD series will take it toll on Canon's position when they see at the same price point there is a better alternative. I like their move with the 100D though.
I'm a Rebel user but I'm one of those on the fence to move up to the 70D or 6D, maybe even the 7D2. I'm hoping the 70D will have a noticeable IQ improvement. Otherwise may just go with the 6D.
they are a market leader because they once deserved it, they could and should be running away with it not merely just a bit ahead
eventually you'll no longer be if you sit around forever though
their good lenses also helped and the 5D2 video helped for that generation
