I hope they pull a big surprise. 7D2 will have no measurable effect on a 5D3, let alone a 5D4. I don't understand why people keep trying to compare the two as competing bodies. They are not, nor will ever be. Not in price and not in use.+100000000000000000000000000000
I think Canon needs to make a statement before 2015. We have the sensors out there. Even if from Sony. I'd love to see a Sony sensor in a Canon system. Talk about the best of everything!
