Canon's 1D C: Under the Hood, is It Really the 1D X's Twin?

Here's an excerpt of Canon Rumor's post on the subject:
I have spent considerable time trying to find someone at Canon to clarify the reports as well as someone to open their EOS-1D C (no one would do that for me!). The information I have received backs up what Canon said at the development announcement of the EOS-1D C, it does in fact have a different hardware configuration inside. While the DIGIC V processors, image sensor and AF module are all identical to the EOS-1D C, there is in fact “reworked circuitry and design to dissipate heat for the 4K recording”.
Interestingly the hardware that is the same, according to the post -- particularly the sensor and processors -- may be the first pieces you'd logically think (not that all of us are video engineers here or anything, but bear with me) would differ between 4K-capable and 1080p-maximum cameras. After all, if those same processors and imager can perform at a 4K level within a different camera, you'd think the 1D X could theoretically also achieve 4K video -- and then probably just overheat or maybe even melt something important really quickly.
I understand why it may be frustrating to own a camera whose innards could be shooting 4K, but can't given the current configuration. Keep in mind -- regardless of what hardware, or firmware, is necessary for allowing the sensor and the DIGIC Vs to achieve their full potential in spatial resolution -- Canon seeks to put a 4K DSLR in our hands. I'd say it's almost unfair to criticize them for how they're doing that, or for not enabling a less expensive camera with some key shared traits to achieve as much. I don't think it's about what parts are the same, or what new parts or new firmware we're paying for: what we're paying for is the final product -- the ability to shoot 4K video.
Personally (not that I can afford it), I think the difference between 4K and 1080p is worth at least $7000. Does anybody else feel the same way? Or do you think the 1D C is really just an unfairly priced, superficially-upgraded 1D X?
