Who Is Norman Osborn's Secret Weapon In Siege?

Remember when we saw the Cabal meet?  There was question as to why they would all listen/follow Norman Osborn's orders.  He reminded them of his little friend waiting outside.  All we got was a glimpse of a shadow.

The speculation has been that he(?) will have the initials "MM."  One of the top runners was Molecule Man (who we just saw in Dark Avengers #10).  Another name that I've heard thrown around is Miracle Man ( also known as Marvelman, who Marvel recently acquired).
 
There's also the image to the left that Marvel has posted.
 
Are you looking forward to SIEGE?
