According to this article at aintitcool, http://www.aintitcool.com/node/57460 Marvel may be trying to get the rights back from Fox for Silver Surfer and Galactus. Reportedly, Fox will lose their rights to DareDevil if they don't have a film started by October. The rights would go back to Marvel. Fox reportedly has designs to do a "Frank Miller Inspired" DareDevil reboot with Joe Carnahan directing. So Marvel may be negotiating to allow Fox to keep the DareDevil rights in exchange for Silver Surfer and Galactus. Marvel clearly had designs to expand their cosmic film universe, and SS/Galactus fits right in with that plan.
