$1199 would be a downright bargain, compared to canon's normal pricing lately. If this comes in at that price point, I'm SUPER excited for the 7d2 because I might actually be able to afford it...
Re: CPUs and AF system. The 7D has dual digic 4, + 1 processor for AF. This has 1 digic 5+, which has "18 x computing power" (see above). Now, I understand that all this is a simplification, and that "power" is a very vague term. But, it doesn't seem inconceivable to me that the camera could process slightly less data at max burst (20.2MP * 7fps vs 18MP * 8fps), AND drive the AF system with the same CPU. Unless there are other, more demanding processing requirements, it would seem to me that 1 digic 5+ is doing the work of the previous 2 digic 4s + unspecified AF chip.
