"Magical" colors: is 5D3 closer to 5D than 5D2 was?

I just came back from Siberia where a local pro told me this story. At first, wedding photographers there used 5D. When 5D2 was released, many switched to it, but got disappointed with its colors compared to 5D and switched back. Most of them still use 5D for better colors compared to 5D2.

5D3 is not yet widely available there, but the rumor among these guys is that the colors of 5D3 are closer to 5D than the colors of 5D2 were. Is this true? Is the "magic" of 5D back after skipping a generation? Or is this just a wishful thinking and the "magical" colors of old good large photocells are gone for good in the mist of time?
