The Marvel comic license may not be out of the realm of possibilities....Medicom used to have both the Comic and Film licenses and now that we're getting Marvel film pieces from HT, its possible they would go after the other side as well, but looking at the possible film licenses that they could go after on both the Marvel, DC and other comic properties side:
Runaways (2011)
Doctor Strange (2012)
Namor: The Submariner (aka Submariner, 2010)
The Avengers (2011)
Iron Man 2 (2010)
Nick Fury (2010)
X-Men Origins: Magneto (2009)
Thor (2010)
The First Avenger: Captain America (2011)
Silver Surfer (2009)
Sin City 2 (2010)
Sin City 3 (2010)
Sgt. Rock (2012)
Spider-Man 4 (2011)
Superman: Man of Steel (2011)
Y: The Last Man (2010)
The Witchblade (2009)
Billy Batson and the Legend of Shazam (aka Captain Marvel, 2010)
Luke Cage (2009)
Iron Fist (2012)
Green Lantern (2010)
The Green Hornet (2010)
The Flash (2010)
The Hands of Shang-Chi (2009/2010)
Jonah Hex (2010)
Green Arrow: Super Max (2010)
Its possible that as comic licenses for DC or Marvel aren't even on the table, they wouldn't have to be.... Not to say that HT will go after all of these licenses but its definitely a lot to choose from.
