Wouldn't the trend suggest that the t6i will be the t5i, with a new name badge and a better kit lens? Maybe they'll up the AF system, but the biggest strength of that system is its customizability, and ability to select and use outer focus points with cross-type reliability. Most (yes, I'm generalizing, but that generalization is based on the target market for the rebel), most rebel users are less-advanced users, and using either full auto, or a program mode, which won't really take full advantage of the AF. FPS definitely won't exceed 70D, I guess no more than 6fps. And body/build will certainly stay rebel. The 7D was already recycled to make the 70D, and it's what, 5, pushing 6 years old? They've gotten plenty of mileage out of that R&D already....
