Ashcan Pete spoiled:
Arkham Horror investigators to feature in Mansions of Madness.
They also show minis for Michael McGlen, and Jenny Barnes on the flash advertisement of the main info page.
I was very glad to learn that they were using the same investigators. that ties the games in very well. It's one of my minor peeves witht he CoC LCG in that the artwork for Arkham characters are not the same people in CoC.
