It makes no sense to replace the 5D3 with 52 MP body based on the 7D2 sensor.
I would take the speculation that this will be a 5DIV with a massive dose of salt.
Going back to the original interview, Canon understands that there are two primary markets: Those who need high ISO sensitivity with excellent noise control (which Canon nailed with the current generation of full frame cameras) and those who want higher resolution (which Canon apparently did not feel was a sufficiently large market to place an immediate emphasis on, but they apparently now feel they need to compete in that market)
I am certain that the high resolution Canon full frame (5D HD?) will not be a direct replacement for the 5D III. This "5D HD" (high definition) may surface in 2015, with the 5D IV (or 5D High Sensitivity) version showing up sometime near the end of the year or more likely in 2016.
(As an aside: apparently the low ISO, high dynamic range market is such a small niche market that Canon doesn't see it as sufficiently large enough to warrant a major release at this time. However, I can certainly see a scenario where the 5D IV/High Sensitivity would see at least a modest boost in dynamic range)
