This has nothing to do with marvel not getting its act together. They can't use Namor because of legal issues.
That’s at Universal.http://screenrant.com/hulk-3-sequels...-namor-rights/It’s slightly more complicated than that. Let’s put it this way – there are entanglements that make it less easy. There are older contracts that still involve other parties that mean we need to work things out before we move forward on it. As opposed to an Iron Man or any of the Avengers or any of the other Marvel characters where we could just put them in.
