I was recently told by a Canon employee (I will not mention their seniority, affiliation, etc., as to protect their identity) that he has seen "hints of a new EOS body" being unveiled at "the 2012 CES show". CES 2012
is scheduled for January 10-13.
The employee I spoke with admitted that he was not privy to product launch information, or "in development" EOS bodies, and that specific launch date details are heavily guarded company secrets. However, he did mention that Canon had plans for a "larger than normal" CES booth/presence this year, with arrangements being made for high level employees and product reps. to be on hand.
It's definitely a "read between the lines" kind of scenario - but interesting none the less.
