I know what I am going to be reading on my way home tonight: Canon released the 1DMrkIV white paper. You can download it here.
Word of caution: White Papers are marketing materials and should be expected to bend, twist and fold the truth in every angle to promote the product. The best example of this was the Canon 5DMrkII White Paper (pre firmware update) which stated that the 5D allowed the videographer total control over the depth of field. Which was far from reality at the time and caused a lot of frustration.
For “real” information, you should read the product manual or wait for my hands on review.
